Abstract

The spread of Synchro-Phasor Unit such as PMU(Phasor Measurement Unit) of each country in power grid represents an evolutionary change in power system measurement, monitoring, control and protection, as phasor measurements hold the promise of providing a fast dynamic picture of power grid status. In particular, synchro-phasor becomes the heart of smart gird transmission from Smart Grid beginning to make its appearance in these days. Recently deployed 'Korea Wide Area Monitoring System (K-WAMS) ß version' in Korea power grid with analyzing and assessing the local and wide area power system condition is introduced and the evaluation of this system is dealt with a various aspects in this paper. The Korean Wide Area Monitoring System (K-WAMS) in the first phase of system proving is composed of eight i-PIU's(Intelligent Power system Information Unit) such like PMU, and central system i-PIS(Intelligent Power system Information System). As in the case of the stressed modern power systems with marginal stability, metropolitan voltage instability and small disturbance stability problem are the most concerned in the Korea power grid, and K-WAMS treats those problems. In the metropolitan voltage instability view point, i-PIU's are installed at three heavily loaded points in generation areas of six routs which, three 345kV substations(Asan, Chungyang, SinJaechun), and at the important point of SPS(Special Protection Scheme) view point, one 345kV substation(DongSeoul) with leased line as a communication network for just suitable data transferring. Moreover to monitor the characteristics of HVDC and wind farm, i-PIUs were installed in Jeju-island. In this paper, the performance evaluation of deployed K-WAMS ß version in Korea power grid is introduced and focuses primarily on the application using i-PIU measurements for grid dynamic analysis.
