摘要
介绍了MCVQ-1型变电站电压无功综合控制系统中模糊边界的电压无功调节判据的应用,指出模糊边界的电压无功调节判据与传统的"#"字形判别方式相比,考虑到电压的因素,从而减少了电压的波动和调节次数。总结了近几年在35-220 kV变电站中的运行经验,采用电压无功模糊调节判据,实现了变电站电压无功的综合控制。在保证电压合格和无功补偿最佳的情况下.使有载变压器分接头的调节次数减少1／3。
The application of voltage and reactive power regulation criteria with fuzzy boundaries in MCVQ-1 substation integrated control system is introduced. Compared with the traditional #-type criteria, the voltage factor is considered to reduce voltage fluctuation and regulating times. The operating experiences of 35-220kV substations in recent years are summarized. The substation voltage and reactive power integrated control using the regulation criteria with fuzzy boundaries lowers one-third of transformer tap regulating times,while the qualified voltage and optimal reactive power compensation are guaranteed.
