4�- OPERATION

4.1.-OPERATING PRINCIPLE

One of the main features of the CDPisthatitcanmeasurealltheenergyflowsoftheinstalla-tion:

Energy consumed by the user. Energy generated by the inverter. Energy consumed or injected into the grid.

Theinverterpowermustbeconfiguredinthedeviceand,throughacommunicationschannel,the CDP can adapt generation to energy consumption with the aim of achieving zero grid in-jection

The CDP generates a database with all the power and energy information for every measuring point, including the inverter’s regulation percentage.

The following functions have also been implemented in the CDP:

Grid injection alarm control. Management of non-critical loads, CDP-G model.

Dualconfigurationofthenetworkparametersforhybridinstallations,CDP-DUO mo-del.

4�1�1�- MEASUREMENT SYSTEM

The CDP measures the user’s voltage and current and uses these values to calculate the consumed power. If the power generated by the inverter differs from that consumed, the unit changes the inverter’s working setpoint to adjust it to the real-time needs of the installation.

4�1�2�- GRID INJECTION PROTECTION RELAY

If measuring the power consumed from the grid, both in single-phase and three-phase installations, the CDP can control a redundant grid current injection protection relay. Relay number 4 is used for this function, by default the relay status is NC (terminals 8, 9 and 10 to the Table 3).

Table 12 describes the parameters that can be configured in the CDP in relation to the control tasks of this function:

Table 12: Configuration parameters for the grid injection protection relay.

Configuration parameters for the grid injection protection relayParameter Description Units

Enable inverse current relay Activation of the inverse current protection -Stop time Grid injection validation time s

Reconnection time Reconnection time sMax. Disconnections Maximum number of reconnections -Disconnect� Timeout Maximum reconnection time s


CDP

If power is injected into the grid during the period defined by the Stop time parameter, relay number 4 is desactivated. (If Stop time is programmed with the value 0 this function remains deactivated). In addition, an orange alarm icon appears on the web site, as shown in Figure 9:

White alarmicon

Orange alarmicon

When the current injected into the grid disappears, after the Reconnection time, the alarm status is deactivated.

4�1�3�- CDP-G MODEL : MANAGEMENT OF NON-CRITICAL LOADS

This functionality allows you to add non-critical loads depending on if more power can be ob-tained from the inverter. This management can be manual or dynamic and is carried out through the use of the system’s auxiliary relays (terminals 11 to 16 of Table 3).

Manual managementisperformedfromtheconfigurationwebsite,fromwhichyoucanviewand modify the status of the relays (Figure 17).

Figure 17:Manual management of non-critical loads from the web site�

When managing dynamic control, the loads are connected based on having met two condi-tions:

Figure 18:Maximum grid contribution.

As soon as the value is greater than or equal to the value programmed by the user, the last relay to be activated will be deactivated.

To ensure correct system stability, a minimum reclosing time (programmable by the user) must pass between the activation and deactivation of two loads or a single load.The order in which loads are activated is another parameter that can be set by the user. The order may be set as: connection by priority or rotating connection.

Connection by priority: In this case the user sets the order in which loads are to be activated.

Rotating connection: Each connection cycle begins with a different load. In other words, the first connection cycle begins by connecting load 1, then 2 and finally 3. The following connection cycle will begin with the load from relay 2, then 3 and finally 1, and so on and so forth.

The disconnection order for both modes is based on a LIFO system in which the last load con-nectedtothesystemwillbethefirstloadtobedisconnected.

Note: See examples of operation in section “7.- CDP-G MODEL: EXAMPLES OF OPERATION”

4�1�4�- CDP-DUO MODEL: NETWORK TYPE IDENTIFICATION

The device can be adapted to the injection parameters, thanks to the digital inputs of the CDP-DUO model, according to the type of network.

When the unit has no active digital inputs, it operates with the injection parameters of Mode 1 (Main).

When digital input 1 is activated (terminal no. 28 in Table 3), the unit changes the injection parametersspecified inMode2(Secondary) of the unit’s web server (See “ 6.3.3.- POWER CONTROL & DATA LOGGER: CONTROL”).

4.2.- APPLICATIONS

The CDP is the ideal unit for managing photovoltaic installations for self-consumption with and without grid injection.Fourtypesofconfigurationscanbedistinguisheddependingonthetypeofgridconnection:

Single-phase connection, the CDP measures the power consumed by the user, the power generated by the inverter and the power consumed from the grid.

Basic three-phase connection, in which the CDP only measures the power con-sumed by the user.

Three-phase connection with monitoring, the CDP measures the power consumed by the user, the power consumed from the grid and calculates the power generated by the inverter.

Thedifferentconfigurationsaredescribedbelow.

4�2�1�- SINGLE-PHASE CONNECTION

The CDP has three voltage measuring channels (VL1, VL2 and VL3) and three current meas-uring channels (IL1, IL2 and IL3) and uses an MC3 current transformer to measure the power consumed by the user (VL1, IL1), the power consumed from the grid (VL2, IL2) and the power generated by the inverter (VL3, IL3).

4�2�3�- THREE-PHASE CONNECTION WITH MONITORING

Figure 23 shows a three-phase installation in which the CDP directly measures the user’s con-sumption, in this case a small-scale industry, by connecting an MC3 current measurement transformer. The power control uses its RS-485 channel to communicate with a CVM-MINI/NET type three-phase measuring unit. This unit is responsible for measuring the power consumed by the grid.

The data gathered by the Data Logger can be used to check the insolation periods of an instal-lation.

Figure 39 shows that during periods in which insolation is minimum, the user’s consumption is taken from the grid, however, it is the inverter that supplies energy during periods with max-imum insolation.

This is the period of maximum insolation during which the energy generated by

the inverter is consumed.

There is no insolation during these periods and energy is obtained from

the grid.Figure 39:Graph showing the operation of the CDP based on insolation�

●Phase

In this section the architecture of the inverter grid connection must be selected. The available options are:

“Single phase” for a single-phase installation with single-phase inverters.

“Three single phases” for a three-phase installation with 3 single-phase inverters .

“Three phase” for a three-phase installation with three-phase inverters.If we select the this option the parameter Three phases mode will appear on the screen, allow-ing us to select the control mode. The options are:

●Min� Power phase, control by minimum power: when this option is selected the CDP sends a production setpoint based on the phase of the minimum consumption.

●Max. Power phase, control by maximum power: the CDP sends a production setpoint based on the phase of the maximum consumption.

●Selected phase, control by set phase: this option allows the user to set a phase such that the CDP will always send the production setpoint to the inverter based on that phase’s consumption. When this option is selected a dropdown menu appears on the screen allowing you to select the phase

●Average power, control by average power: this option takes an average of the con-sumption of the three phases and sends a production setpoint to the inverter with the value of the average power.

●Allow compensation

Note : This function is available when the unit is working with more than 1 inverter.

This function allows you to manage several inverters independently to obtain the maximum generation from each of them.

Example: For example, an installation with two 5 kW inverters connected to 2 strings of inde-pendent panels on a gabled roof in the east-west direction and consumption of 4 kW.If in the morning, inverter 1 can generate 5 kW but inverter 2 can only generate 1 kW, because

50

CDP

Instruction manual

the panels are not receiving sufficient radiation, rather than requesting 2 kW from each inverter, the CDP will request the maximum power from the inverter that generates the least (1 kW) and the remainder will be requested from the inverter which generates more (3 kW), to try to reach the required consumption.To do this, it will gradually increase the regulation percentage of both inverters at the same time until both generate a total power equivalent to that required by the load.

Note: In three-phase systems, the connection of a CVM Mini is mandatory to measure the power consumed/delivered to the mains.

●Enable remote control

Note: on activating this option, the options injection margin and allowed injection are deac-tivated.This option facilitates the remote control of the setpoint value, through the unit’s digital inputs.Thevalueofthedigitalinputselectedisapercentagethatitaddedtothefixedsetpointvalue.By default, the value of the digital inputs are,Table 17 :

Table 17: Default values of the digital inputs�

Digital input Default value1 02 303 604 100

Example: In an installation with a consumption of 600W and a 4kW inverter, the setpoint that CDP calculate would be15%.

No input activated: the CDP maintains the calculated setpoint. Input 1 activated: the CDP maintains the calculated setpoint. Input 2 activated: the CDP adds 30% to the calculated setpoint (the new set-point will be 45%). Input 3 activated: the CDP adds 60% to the calculated setpoint (the new set-point will be 75%).Input 4 activated: the CDP sends the 100% setpoint to the inverter. (100% will be the maxi-mum setpoint).If several digital inputs are activated, the CDP will always take the highest as a reference.

●Injection margin

Youcanconfiguretheminimumpowerinjectedintothegridoverthe%oftheconsumedpowerwith this parameter.

Example: if consumption is 3 kW, and the injection margin is 10%, the CDP will try to take 300 W from the grid and will therefore send the inverter a set-point so that it will provide 2700 W.

TwodifferentconfigurationscanbeprogrammedfortheCDP-DUO model, using the Injection margin parameter, according to the type of network that is present (Figure 55).


CDP

Figure 55: Power Control parameters (CDP-DUO)

When the device has no active digital inputs, the CDP-DUO operates with the injection para-meters of Mode 1 (Main).

If you activate digital input 1 (terminal no. 28 in Tabla 3), the unit will operate with the injection parametersconfiguredinMode2(Secondary).

●Allowed injection

InthissectionitisconfiguredthePercentageofinjectioninexcessoftheconsumedpower.This value can be positive or negative with respect to the photovoltaic power.

The negative values are used for hybrid networks, renewable and non-renewable networks (UPS, generator set, grid, etc.), where it is important that the non-renewable network is not permanently connecting and disconnecting. A negative Allowed injection forces the non-re-newable energy source to constantly supply a residual percentage of the consumption.

Example: For example, an installation with one 5 kW inverter and a 100 kW generator set.Consumption is 4 kW and one of the loads needs to be permanently supplied.In this case, the variable Inverter power will be programmed to 5000 W and the variable Allowed injection to a value of -1%. Therefore, the generator set will always be connected, supplying 50 W.

TwodifferentconfigurationscanbeprogrammedfortheCDP-DUO model, using the Allowed injection, according to the type of network that is present (Figure 55).

When the device has no active digital inputs, the CDP-DUO operates with the injection para-meters of Mode 1 (Main).

If you activate digital input 1 (terminal no. 28 in Tabla 3), the unit will operate with the injection parametersconfiguredinMode2(Secondary).

●Enabled Power Factor (CDP-DUO Model)

When you activate this option, the CDP-DUO sends setpoints to compensate the reactive ener-gy being consumed. This function is only available with FRONIUS inverters and the FRONIUS MB communications protocol.

●Enable reverse current relay

Enable this option to activate the reverse current relay protection. If the device measures a neg-ative power value in the grid, it desactivates the inverse current relay to disconnect the inverter.This relay acts as redundant protection against a possible grid injection.The relay has 3 terminals and can be NO or NC, depending on how it is connected.

In three-phase mode it is essential to install a CVM Mini to measure the grid.

When you enable this option, an external analyser is used as the measuring unit, instead of the CDP.The CDP automatically calculates the values of the photovoltaic production using the consump-tion measurements (Load analyzer) and the grid (Grid analyzer).Therefore, enabling this option is only of interest in installations which already have a CVM power analyzer installed, which is not communicating with any system (software or automaton) and the user wants the CDP to read the values measured by this analyzer.

7.1.- SINGLE-PHASE INSTALLATION WITH 1 LOAD TO BE CONNECTED

We start with a single-phase installation in which we want to use the excess photovoltaic pro-duction to supply 1 non-critical load, such as a heat pump.

Load 1: 5000 W heat pump

The goal is to activate these loads during times in which there is a production excess, thus re-ducing energy costs.

This is the start data:Table 18:Start data

As shown in Figure 71, we can see that although the inverter is 10 kW the existing radiation only allows it to produce 9 kW, so to get 10 kW of consumption it will have to take 1 kW from the grid.

In this situation the CDP-G maintains the system without adding or removing any loads for the amountoftimeconfiguredintheReconnection time variable, in order to achieve system sta-bility (in this case 5 minutes).
