Abstract:

电网仿真初始运行方式是影响计算结果的主要因素之一。由于SCADA覆盖了电网主要运行设备,因此可以将SCADA数据作为建立电网仿真计算运行方式的主要数据源。然而,仅仅依赖SCADA数据建立的初始运行方式与实际系统相比可能存在较大偏差。随着广域实时动态监测系统(WAMS)逐步在电网中的广泛应用,由其采集的电网实时动态数据也成为建立仿真初始运行方式的主要数据源之一。作者提出了一种利用SCADA数据和WAMS数据建立电网仿真计算运行方式的方法。该方法计及了SCADA和WAMS的特点,确定了SCADA、WAMS与仿真计算数据库间的数据流,具有明确校核调整机制。利用该方法所建立的运行方式可以经受SCADA、WAMS实测数据的反复校核。
