摘要
换流站无功补偿、无功平衡对交直流系统正常运行有重要影响,是高压直流输电系统设计的重要内容。论述了换流站站内的无功功率平衡,分析了换流站无功功率消耗的计算方法,讨论了交直流系统的运行参数和运行工况对换流站无功消耗的影响,介绍了交流系统强度及其无功支持能力对高压直流输电无功平衡的作用,结合交流系统无功补偿能力,根据系统强度分析了换流站无功补偿应合理选择的无功补偿装置,并讨论了各种无功补偿装置的类型及其优缺点,最后,总结了无功补偿容量和无功分组的确定原则和方法。
Reactive power compensation and reactive power balance of converter station has very important influence on the normal operation of AC and DC system and plays an important role in the design of HVDC project.The Reactive power balance in converter station is expounded and calculation method of reactive power compensation is analyzed, and the influences of the specific operation parameters of AC and DC system and operating conditions to Reactive power consumption of converter station are discussed in this paper.AC system strength and the AC system reactive power compensation capacity effect to reactive power balance of HVDC are introduced.Combining AC system reactive power compensation capacity,according to system strength,the Reactive power compensation should choose reasonable reactive compensation devices,thus several types of reactive power compensation device are introduced and their advantages and disadvantages are analyzed.At last,the study summarizes the principles and methods of reactive compensation capacity and reactive power grouping.
