风力发电近年来在国家的大力扶持下获得了巨大的发展,由于风能的随机性、间歇性特点以及风机的运行特性,对电网电压稳定性的影响也越来越显著,尤其在大规模风电接入薄弱的末端电网时电压稳定问题更为突出。风电机组的连接方式、长距离... 风力发电近年来在国家的大力扶持下获得了巨大的发展,由于风能的随机性、间歇性特点以及风机的运行特性,对电网电压稳定性的影响也越来越显著,尤其在大规模风电接入薄弱的末端电网时电压稳定问题更为突出。风电机组的连接方式、长距离输送以及机组无功调节能力差,是风电无功和电压调整困难的主要因素。因此在风电场建设自动电压控制系统,对风机、无功补偿装置、有载调压变压器进行统一协调控制,实现风电场并网点电压和无功功率的自动调控,不仅能保证电网安全稳定运行、提高电压质量,还可以减少有功损耗、提高风电场经济效益。 展开更多

The dynamic reactive power compensation equipment in Jiuquan Wind Power Base of above 10 GW consists of three different types of compensation devices, including: static var generator (SVG), thyristor controlled compensator (TGR) and magnetically controlled reactor (MGR). The lack of experimental verification of performance is not conducive to voltage/var management or full utilization of device capaci- ties. In order to solve the above problems, the compensation device performance test was performed. The test items and procedures were selected based on related national standards with the consideration for different grid structures and wind farm operation modes. The testing contents included dynamic regulating range, active power loss, dynamic response time, and harmonic voltage level. Three types of compensation devices installed in different wind farms, namely SVG, TCR and MCR, were chosen and tested. The performances were compared and analyzed according to the field test results. 展开更多
