摘要
送端电网在向受端电网输送大功率电量的同时,还要向本地区电网提供电力支持满足地区用电需求,因此送端电网的结构对系统的稳定性影响甚大。指出应从电源接入系统的电压等级以及电源接入系统的母线接线方式这两个方面考虑电源接入系统的方式;论述了送端电网的互联问题,指出送端电网不宜互联紧密;讨论了送端电网与受端电网的连接问题,指出应缩小送端电网和送端电网的电气距离,并同时在高一级的电网规划中考虑低一级电网的规划,提高电网的输送能力。
Not only is electrical power transported to import power network but also electrical power is offered for area need. So the configuration of export network is very important. At first, this paper points out that the voltage grade and the generator connection mode which is connected into power system must be thought over. Then, it indicates that the connection mode of export network can＇t be compact united. Finally, the connection mode between export network and import network is discussed. It indicates that in order to improve power system transmission capability, electrical distance must be reduced. Also, it points out the lower voltage power system programming must be taken into account when the high voltage power system programming is made.
