摘要
1000kV系统用电容器补偿装置的电压等级确定为110kV,容量为210Mvar。由于该电压等级的大容量电容器装置在国内属首次使用,在国际上亦无先例,因此其在参数选择、结构、配置、配套件选择上都将与我们习惯使用的补偿装置有着很大的不同,如串段数多,并联数大等,也具有许多不同的特点。文章介绍了1000kV系统用电容器补偿装置的特点;对其参数,如电容器装置串联数、装置额定运行电压、安装容量、单臂并联数、单台电容器容量、电容器装置桥差保护等的选择原则或整定原则进行了详细介绍,以供设计、制造和运行部门参考。
The voltage grade 110 kV for condenser compensation installation in 1 000 kV power system is determined with capacity 210 MVAR. Since the high capacity condenser installation with this voltage grade is firstly used in China,and does not have precedent in the world. There is great difference with conventional compensation installation on parameter option,structure,disposition and supplemental option,and there is a lot of different characteristics such as great number of series and parallel connections etc. This paper introduced the characteristics of condenser compensation installation in 1 000 kV power system. The principles of selection and setting for the parameters,such as the series number of condenser installation,rated operation voltage,installation capacity,the single arm number of parallel connection,single condenser capacity and condenser installation bridge differential protection etc.,were introduced in detail,which can offer to the departments of design,production and operation as reference.
