| 9. | It is researched for the influence of the existing reactive power compensators in sichuan power to system voltage under different disturbances . it is constituted the capacitance and place of installing the dynamic reactive power compensators in sichuan power system 研究四川电网现有的无功补偿装置在电网发生各种扰动时对电网电压的影响;研究动态无功补偿装置对提高电网电压稳定水平的作用;制定动态无功补偿装置在四川电网中的装设容量和地点。 |
| 10. | With the development of the electric power system , static - state reactive power compensators ca n ' t have met the requirements of the actual production and operation , and the trend to the fast and dynamic compensation for reactive power become greater and greater . since ertan hydroplant and 500kv transmission systems in sichuan power system have been operated , many power plants of load center are forced to halt during the high - water period , because the great deal of power is transmitted to far - distance load center . thus the load center loses voltage sustentation and the level of the system stabilization is debased greatly 四川电网的二滩水电站和500kv输变电系统投入运行后,由于二滩水电站的大量电力远距离输送至负荷中心,迫使负荷中心的火电机组在丰水期大量停机,使负荷中心失去电压支撑,大大降低了电网的电压稳定水平;同时,因为四川电网中的无功补偿装置全为静态无功补偿电容器(或电抗器) ,这些设备只能在系统正常运行状态下起到无功补偿和电压支撑的作用,而在电网出现事故时,不但不能起到电压支撑作用,反而会促使电网电压崩溃事故的发生。 |
