摘要
介绍了交流特高压试验示范工程的高抗、低压电抗器、低压电容器等无功补偿设备及特高压变压器的调压方式,分析了示范工程无功功率与电压运行控制要求及其影响因素。结果表明,特高压联络线功率波动幅度较大,易引起1 000/500 kV母线电压出现较大的波动,导致联络线与两侧500 kV电网较大的无功功率交换;两侧500 kV系统电压及特高压主变分接头位置、特高压线路事故解列等均对无功功率与电压调整产生影响。在此基础上提出了示范工程无功功率与电压控制策略及运行建议。
Some kinds of reactive power compensation equipment such as high voltage reactors, low voltage reactors and capacitors and voltage regulation method of UHV transformers used in pilot demonstration project of UHV are introduced in this article. The requirements of reactive power or voltage control and their influencing factors in the operation of demonstration project are analyzed. Results show that the power of UHV tie line has a large fluctuation range, causing a large voltage fluctuation in 1 000/500 kV bus and a large reactive power exchange between the tie line and 500 kV power grids on its both sides. The 500 kV system voltage level, UHV transformer tap positions and splitting accidents on UHV lines have an impact on the reactive power and voltage regulation. Reactive power and voltage control strategies, and operational recommendations of the demonstration project are also presented in this paper.
