南方电网无功补偿配置原则与标准探讨

Discussion on Technical Principles and Standard for Configuring Reactive Power Compensation Equipment of China Southern Power Grid

南方电网是典型的交直流混合运行电网,结构复杂、联系紧密、运行难度大,电压运行水平对维持整个电网的安全稳定运行至关重要。合理的无功补偿配置在平衡系统无功功率、调节系统电压运行水平上起重要的作用。南方电网公司之前发布的涉及无功配置导则的内容尚不全面,在实际运行中也发现了一些问题。通过对南方电网无功电压现状的分析和实地调研,指出交流电网无功补偿配置及实际运行中存在的问题,并结合国内已有的相关原则、标准,对有别于传统考虑或存有异议的原则进行了重点研究,提出了今后工作中应遵循的原则和建议。

China Southern Power Grid （CSG） is a typical AC and DC comhined power grid with complex structure and difficult operalion. The wJltage operational issue is vital to maintaining the security and stability of the entire power grid. Reasonabh, reaclive power compensation configuration plays an important role in balancing reactive power and regulating the voltage level. The standards of reactive power configuration issued by the China Southern Power Grid Company are not comprehensive enough and some problems are found in actual applicalion. On lhe basis of an investigation and analysis of the reactive power and voltage level in CSG, the problems in reactive power compensation eonfiguration and actual operation are summarized. Combined with existing domestic principles arid slandards, some suggestions and principles are proposed for futrre work.
