Background and Information of KHNP (1/2)
Korea Electric Power Corp. (KEPCO) officially split up its power
generation sector into 6 separate companies on April 2, 2001 by the
Korean government’s electric power industry restructuring program.
The goal of the restructuring is to provide users with stable supplies
of high-quality and low-cost electricity by maximizing the
competitiveness and efficiency of the power generation companies.
Korea’s electric power exchange market have been operating since April
2002. Although it is currently a Cost-based pool, it will be changed into
TWBP (Two Way Bidding Pool) market by April 2004
As one of the subsidiaries, KHNP has been formed combining hydro
and nuclear generating facilities of KEPCO.
operate 18 nuclear reactors in 4 sites, and 16 hydro plants
2 new reactors are under construction
plan to build an additional 10 reactors by 2015

Installed nuclear capacity : 15,716 MW (as of the end of 2002)
29.2 % of the nation’s total installed capacity
Nuclear power output : 119 billion kWh (in 2002)
38.9 % of the country’s electricity consumption
Average capacity factor of NPPs : 92.7 % (in 2002)

PI Introduction Scope
Server Side ▪PI UDS : Data Storage (6 PI Servers)
Interface Side
▪PI RDBMSPI I/F : Site Interface I/F
▪PItoPI I/F : I/F between head office and each site
▪PI API : App. I/F (Manual input, SAP CO module I/F)
▪PI Activeview : Web I/F
▪PI RLINK : SAP PM module I/F
Client Analysis
Tool
▪PI DataLink : MS Excel I/F
▪PI PrecessBook : Mimic Implementation
✤ We intended to introduce PI ICE for web interface but PI Activeview
was finally installed instead of PI ICE to improve speed on the web.

Interface with SAP PM through RLINK
PI RLINK provides an interface between PI and SAP PM
Trigger based SAP Transaction
Transaction is triggered by the alarm tag
Automated PM notifications
Measurement document creation in SAP PM
Additional tags are needed for alarms, PM notification number,
and measurement document number.
No way to transfer PI analog type data to SAP frequently,
through RLINK
In case of manual input, the additional step resetting the alarm is
necessary
Can not deliver any real time analog data from PI to SAP

Trouble Shooting on ProcessBook (1/2)
Problem
: DataSet expressions are truncated after the pdi file, which
include datasets, is copied to another PC.
(PB version 2.31)
Solution
: After upgrading the UDS server from version 3.3.361.93 to
version 3.3.362.47, the problem was disappeared.

Trouble Shooting on DataLink
Problem: PI time strings (‘Y’,’T’, ‘*’, etc.) are not work in Excel properly
(DL version 2.1)
SolutionUse Excel functions such as ‘today()’, ‘Now()’, etc., instead of PI time string
OR
Use the Application.CalculateFull method in VBA script OR press ‘Ctrl+Alt+F9’ key combination in the Excel sheet.
Sangyoung Mo, et al.21
Trouble Shooting on Manual-Logger(1/3)
Problem
: Font Broken in Manual-Logger screen (version 1.3)
Solution
:not yet
Because of this problem, we had to develop API
applications instead of Manual-Logger to provide
manual input function .
Sangyoung Mo, et al.24
Conclusions
PI is an important data path among KHNP ERP system, plant
computer, and other legacy systems.
Concept of information system was changed after introducing PI
system
Scope : Individual plant → Whole company
Objectives : Business function based → Business process based
Implementation : S/W development → Package configuration
PI began to change many people who ware opposite to PI, with
impressive capabilities.
Although there is some problem and additional necessary functions,
we don’t doubt PI system is very flexible, easy to use, and powerful.
PI agencies and customers must have correct understanding of all
features of each PI package as well as OSIsoft, prior to PI introduction.
The end.
