765[Kv] 변전소 시뮬레이터를 위한 조류계산 프로그램에 관한 연구

다국어 초록 (Multilingual Abstract)

- Power system is analyzed by three methods of load flow, fault calculation, and voltage stability. Among there, load flow is calculated to flow of power in power system at steady state. But, load flow is difficult to analyze to flow of power in substation, because power flow frequently alter by various equipments such as circuit breaker, disconnect switch and shunt reactor. Particular, in 765[kV] system, because of form of 1.5CB for stable operation, structure of substation has been very complex. In this paper, we describe technique for application of load flow algorithm in simulator for 765[kV] substation. For this technique, we built each database for various equipments and considered form of 1.5CB. Data as form of bus and line, for application of load flow, are acquired from built database, and then calculate load flow in substation. And, results of load flow are outputted in screen of operator console program.
