广东电网研究无功规划，除满足无功平衡和电压质量要求外，提高系统稳定性，预防大面积电压崩溃也是研究的重要目标。在无功规划的基本原则和思路基础上，提出了输电网无功规划的新方法：静态无功平衡结合电网特点分析无功负荷系数，从而得到无功负荷，并借助电压相关指标合理划分无功平衡区域；动态无功规划通过直流受端系统强度、静态无功电压裕度以及电压稳定校验等明确电网薄弱区域后制定配置方案，并对该方案进行论证。该方法已在广东输电网无功规划中得到应用。

Besides being satisfied for requirements of balance of reactive power and voltage quality,improvement of system stability and prevention on extensive voltage collapse are both important targets of studying reactive power planning for Guangdong power grid.Based on basic principle and thinking of reactive power planning,a new method for reactive power planning of power transmission grid was proposed which was to combine balance of static reactive power with characteristic of the power grid to analyze reactive power load coefficient so as to obtain reactive power load and reasonably divide balance areas of reactive power by means of related index of voltage.Meanwhile,configuration scheme for dynamic reactive power planning was formulated after confirming weak area of the power grid by verification on intensity of direct current receiving end system,margin of static reactive power voltage and voltage stability,argument on this scheme was conducted as well. This method has been applied in reactive power planning of Guangdong power transmission grid.
