Transient Contingency Screening of Large Power Systems Using TEPCO-BCU Classifier

摘要

Retrospectively, power system blackouts, which were representatively occurred in North America and Europe, have drawn a great concern of security of public electricity supply, raising the interests of technical robustness and stability of power system network in the restructured electricity industry. For getting rid of these kinds of technical concern, world-wide power system operators have turned their operational interests into power system security monitoring so that new business practice is getting to be embedded into power system operation practice to provide more secured electric energy supply. Recently, as part of EMS research project, Korea Power Exchange (KPX) have collaborated with Tokyo Electric Power Company (TEPCO) in evaluating TEPCO-BCU Classifier which was developed for on-line dynamic security analysis by both TEPCO and Bigwood System Inc. At the initial collaboration stage last year, TEPCOBCU Classifier is evaluated by studying transient screening of 1,200 contingencies, which are now managed in operating Korea power systems. This paper will describe what are done in our evaluation test, and then both test results and validation outcomes are also presented in our discussion. Finally, some remarks from KPX engineers are mentioned as our closing description for the capability of TEPCO-BCU Classifier as the on-line implementation tool of transient stability screening.
