设计了地区电网变压器经济运行的实时控制系统。该系统根据变压器经济运行理论,利用 监控与数据采集(SCADA)系统采集的实时数据和短期负荷预测结果,并考虑实际运行中变压器投 切次数的限制,在线决定变压器的经济运行方式,并通过SCADA系统对变压器进行投切操作。该 系统与SCADA系统协同工作,充分利用了SCADA系统的高可靠性,并且不需要开发新的硬件, 因此具有开发周期短、使用方便、运行可靠的优点。在实际工程应用中取得了良好效果。 Designed a real-time control system of regional power network transformer economic operation. Based on the economic operation theory of transformer, the system realizes the real-time data and short-term load forecasting results collected by SCADA system and considers the limit of transformer switching times in actual operation, determines the economic operation mode of transformer online, Transformer system for switching operation. The system and SCADA system work together to take full advantage of the high reliability of SCADA system, and does not require the development of new hardware, and therefore has the advantages of short development cycle, easy to use and reliable operation. In the actual project has achieved good results.
