Large-scale PhotovoltaicPower Generation Systems

Our photovoltaic power generation systems provide eco-friendly energy.

■ Maximizing Output Power from Photovoltaic Power Generation

High-efficiency three-level inverter with our original RB-IGBTAt Fuji Electric we develop and manufacture high-efficiency power conditioner systems (PCS) in-company using our unique proprietary reverse-blocking insulated gate bipolar transistor (RB-IGBT) technology. Our power conditioners, which are at the industry’s highest level and use the maximum power point tracking control (MPPT) that we have refined through long development, enable maximum output power from photovoltaic power generation.

■ Total System Construction from PCS to System Interconnection

Fuji Electric offers a wide product lineup from high-voltage and extra-high-voltage interconnection facilities that we have developed as a heavy electrical equipment manufacturer to supply-and-demand monitoring and PCS units. We support total system introduction of photovoltaic power generation facilities for our customers.

■ System Stabilization TechnologyPower stabilizers, private power generators, and hybrid power supplies such as wind power generation and fuel cellsFuji Electric has developed its system stabilization technology for more than 20 years.We make use of various types of power supply equipment such as private power generators and wind power generators and power accumulation technology developed for UPS to supply stable power by combining power supply types tailored to each region.

■ Secure Support System in Japan and Abroad

Our service engineers provide secure maintenance support for customer facilities from Hokkaido to Okinawa in Japan and at international service locations.

Our photovoltaic power generation systems provide eco-friendly energy.

As the PCS is the core of the system, we provide a large-capacity PCS of the highest efficiency that incorporates advanced power semiconductors.(The series lineup was reinforced with the addition of a new 500 kW model.)

■ Features

Adoption of new IGBT and new circuit system World’s highest efficiency 98.5% (DC 1,000 V product)

Single unit capacity 1,000 kW

Standard FRT function

New IGBT module

New three-level conversion circuit

Reduction of power loss

Fuji Electric commercialized the world’s first three-level module in which a new RB-IGBT* and an existing IGBT are integrated in one package.Application of this new module to a new three-level conversion circuit enables a large reduction both in power loss and in the number of parts, resulting in high efficiency and low noise in the equipment.

＊: RB-IGBT: Reverse Blocking-Insulated Gate-Bipolar Transistor

Compared to existing products, our new power conversion technology, which uses a new three-level conversion circuit in the new module, reduces switching loss in the IGBT device and also reduces filter loss by reducing to one half the harmonic content in PWM waveform outputted by the inverter. This results in the world highest efficiency of 98.5% (DC 1,000 V product).We have also achieved EURO efficiency of 98.2% (DC 1,000 V product).

Fuji Electric provides a substation type of PCS that can be installed outdoors.A switchgear, a step-up transformer, and PCS that can be installed outdoors are integrated on a common base in a single unit. This eliminates the need for a building for storing panels and air-conditioning facilities. Since this substation is transported to the site as an integrated unit, on-site construction costs can be greatly reduced.With the installation of an optional fuse for a DC branch in the PCS, the panel output collected in the current collection box can be connected to the PCS as is.

Fuji Electric successfully developed a PCS with a single unit capacity of 1,000 kW.For large-scale photovoltaic power generation systems, this large single unit capacity enables the number of PCS units to

be optimized, resulting in significant reductions in construction and building costs.

The fault ride through (FRT) function that is becoming essential in PCS for large-scale photovoltaic power generation is provided as a standard function.Even if a three-phase or two-phase short circuit accident

occurs in the system, the inverter can output three-phase current in a specified range to suppress power supply variations in the system.

Reliability

A monitoring unit quickly collects information on proper photovoltaic power generation and the state of each component.

■ Features

■ System Configuration Example

The SCADA system has the highest quality and cost performance in the industry.The system has many features such as a web function, multilingual function, high speed, extensibility, and reliability.The system can be applied to a large-scale power generation system with several to more than 400,000 I/O points.

High speed ExtensibilityOptimal performance is achieved every time.High-speed data collection and display are achieved even in large-scale systems by optimizing every communication and reducing unnecessary communication.

The number of signals can be extended from 75 to 400,000.Various systems from small- to large-scale configurations can be supported. Also partial system introduction is possible to reduce initial investment.

A system with minimal data loss is achieved with a PC-based configuration.Communication functions and server functions can be provided in completely redundant configurations to build a system that is safe, secure and trouble-free, even in the event of any malfunctions in a PC or in the network.

● Real-time information on plant status can be accessed from anywhere in the world at any time. (Web connection license is provided)

● Language switching is based on a table system for easy switching to other languages. (For display, Windows fonts are used.)

Web functions and multilingual functions

Graphic screen display

A smartphone can be used as a maintenance management tool for facilities.Trends and alarms can be checked through a wireless Windows remote desktop connection.

Description of verification tests

Tarama Island (Okinawa)

• 6 islands in Kyushu (verification research in progress)• 3 islands in Okinawa (verification research in progress) <Case Study on Tarama Island in Okinawa>Our lithium ion capacitor equipped stabilizer was introduced to enable high charging and discharging output and high reliability.

Fuji Electric also develops renewable energy solutions such as photovoltaic power generation and wind power generation for isolated islands. These microgrid configurations can achieve balanced operation with diesel power generation using a system with an advanced high-performance power PCS and a lithium ion capacitor mounted stabilizer. We participate in many verification tests aiming to reduce CO2 emissions and power generation costs.
