Abstract

The most recently developed 'PMU and WAMS' in Korea with basic architecture and functions to analysis and assess the local/wide area power system condition as a one of various IT projects is introduced, and the integration of IT application systems in the near future will also discussed in this paper. The WAMS project is divided into several phases, where for the first phase; the work will be focus only on wide area measurement and monitoring system. K-WAMS, Korean Wide Area Monitoring System, is composed of many PMU's, middle and higher system which are formed hierarchy structure. The primary target of developed system in this phase to prepare the wide area monitoring/protection/control system foundation based on PMU. There are many serious problems of power system in each country. In the case of Korea, metropolitan voltage instability and low frequency problems are the most important and this system deals with those problems with basic concept, RT3DA(Real Time Data Acquisition, Real Time Data Analysis, and Real Time Data Assessment). Korean PMU is called i-PIU, Intelligent Power system Information Unit, which plays precisely measurement and data transfer roles from power system field data. Middle and higher systems are called i-PIC, i-PIS respectively. The real time data management is considered very important in this system, K-WAM, which is operated on real time and treats real time field data from power system. i-PIC, Intelligent Power system Information Concentrator, which is settled each local area, can handle the real time data of field system and monitor the each substation of settled area in RCC level. i-PIS, Intelligent Power system Information System, located in NCC level consists of local/wide area 2D/3D monitoring viewer part, real time power system security assessment parts, early warning part using Alarm/Event part, and reporting part. All developed system follows IEEE C37. 118 for synchro-phasors for power systems. K-WAMS project keeps going to next phase which has Verification and Validation Test and an establishment of data and communication standardization.
