摘要
为缓解500 kV降压容量不足、减轻500 kV变电站供电压力、加强220 kV网架结构和供电的安全可靠性,除加快并落实500 kV变电站布点及配套的220 kV输变电工程外,将广东电网早期接入500 kV电网的电源,通过合理经济的改造后接入220 kV电网是较为科学、有效的方法之一。对广东电网接入500 kV电压层级的电源进行逐一排查,分别从改造需求、改造时机、改接方案经济比较及可行性等方面进行研究,提出需要进行改接的电厂,对促进改接工程的实施具有较好的指导作用。
In order to relieve the insufficient of 500kV down capacity,reduce the pressure of 500kV transformer substation,enhance the safety and reliability of 220kV power grid, except speeding up the 500kV transformer substation setting and its accessional 220kV project, reconnecting generation unit from 500kV power grid to the 220kV is also the scientific and effective method. Investigate the generation units connected to 500kV voltage in Guangdong power grid,study them from reconnected demand,reconnected plan economy and feasibility, propose the generation grid which need to reconnect. It is also helpful to promote the implementation of practical reconnected project.
