摘要
针对1000kV特高压交流变电站主变低压侧无功分组多、占地面积大带来的工程站址场地选择受限等问题,提出将无功补偿装置直接接入500 kV母线的设计方案。对无功补偿装置直接接入500 kV母线的各种接线方式进行了对比分析,调研了设备供货能力,研究了布置方案,进行了全寿命周期的对比分析。结果表明,该方案不仅可以起到提高单组电容器、电抗器容量,减少无功补偿设备占地面积的作用,还可降低能耗。
Site selection is often difficult for the 1 000 kV UHV AC substation due to its many-grouped reactive power on the low- voltage side of main transformer and the large space occupation. A solution to this problem is proposed in the paper to directly connect the reactive power compensators to the 500 kV busbar. Based on a comparative analysis of various wiring modes of reactive power compensation devices connected directly to 500 kV busbar and an investigation of the device supply ability, different layout schemes for the connection are studied and compared in terms of life cycle. The results show that the solution can not only improve the capacity of the capacitor and reactor, and reduce the floor space of the reactive power compensation equipment, but also save the energy.
