摘要
为有效解决超高压长距离输电网的无功调节、暂态过电压、线路空载(轻载)损耗等问题,该文以一台采用自取能控制方式的产品级800kV超高压磁饱和可控电抗器(MSCR)样机为例,对其动态特性进行详细分析,并提出在控制系统和取能线圈之间增加5次和7次滤波器的谐波抑制方法。详细分析MSCR的基本结构及其工作原理,阐述了MSCR的本体特性、控制特性及阶跃特性,并对其谐波抑制进行了实验分析,对其动态特性进行了实验研究。研究结果证明所提方案的可行性,为分析特高压磁饱和可控电抗器的动态特性及谐波抑制提供理论依据。
In order to solve the problem of reactive power regulation,transient overvoltage,light load loss and other issues of the EHV long distance grid,the dynamic characteristics of one product level 800kV EHV magnetically saturation controlled reactor using self-power supply control system are analyzed,and the harmonic suppression method by adding 5th and 7th filters between the control system and the energy supply coil is proposed.Firstly,the mechanical structure and operating principle of the MSCR are analyzed in detail.Then,the body characteristics,control characteristics and step properties of the MSCR are expounded.Finally,the harmonic suppression is analyzed by experimental method.The dynamic characteristics are studied by experimental method,and the correctness of the proposed harmonic suppression method is verified.The theoretical basis for the analysis of dynamic characteristics and harmonics suppression of the EHV MSCR are provided by the study results.
