The role of protective relay with correct setting value is very important for the reliable operation of power : system. The setting process of a protective relay is difficult and requires hard work of calculations. Therefore, KEPCO as been using PROSET2000, a computer program system, in order to automate the setting process of protective relays in power transmission network since 2000. This system has a database and relay setting modules for each type of realy with coresponding Human and Computer Interaction(HCI). For the setting of a new type of relay, it require a new module, a HCI and a database table corresponding to the new relay. But it's update is not easy in case of new type of relay. This paper discussed the update method introducing a concept of Open Interface. It addressd a method to make a new HCI for new relay in view of object-oriented method using UML(Unified Modeling Language). Using the UML, we updated the PROSET2000. HCI screens for a new relay is generated automatically using the information of the new relay stored in the database. And, the database management module is upgraded to solve problems in manage and maintain the database in view of Open Interface.

The setting of protective relays, which is critical to the system security, requires a huge volume of data and a lot of repetitive calculations. Therefore computerization of this process, named PROSET2000 is in progress in KEPCO. PROSET2000 is based on a power system protection database. The database must accomodate a variety of protective device data efficiently, which need be viewed and updated with ease. This paper suggests several database management functions for PROSET2000.

PROSET2000 that is integrated protective management system had developed and used in order to automate the setting process of protective relays in transmission system protection. PROSET2000 have database for relay setting and automated for relay setting program within. This paper proposed PCM current differential relay setting program point of Object Oriented Programming paradigm using Unified Modeling Language about additional relay in PROSET2000. Nevertheless each relay uses same current differential but setting method is different. This paper discribed different thing about setting method of each relay and evaluated more effective and corrective relay setting program using UML.

One of the most important requirements for the development of computerized relay setting system is its openness to abbommodate the various changes like new panel additions. This paper describes the relay settein-coordination system(PROSET2000), which has an open system architecture and adopts the dbject oriented programming paradigm. Its main features include the intelligent fault type identification, automatic running of the short circuit analysis, ren-time rulebase modification, automatic documentation, ect.

Since faults often occur on power system, relay protection has become an important part to protect the equipments of power system efficiently and safely. Database can store the data about the relay protection efficiently, and these data must be shown to users through the web. Proset2000(an overall program system to protect power system) can realize this function in some measure, but it needs to be developed. This paper is about the further development of Proset2000. In this paper, web of Proset2000 is made by ASP programming technology, and users can browse and search the useful data through the web. There are some new functions, such as the summary of setting values, the message board and the management of administrator.

The paper presets the improvements of MMI at the PROSET2000 correction program which is totally computerized system of the power system protection. The Base Form that is an open interface is developed to be able to compose the screen by reading the input screen from the database. It also is developed to be suitable for the environment of the Graphical User Interface instead of the DOS window when the users do the pannel settings. Program development in this paper is designed by Unified Modeling Language(UML) techniques.
