浙江电网网架结构及分层分区方式研究

Research on Hierarchical-regional Principle and Structure of Zhejiang Power Grid

结合浙江电网的运行实际并借鉴国内外电网建设与运行经验,对浙江电网220kV网架架构及分层分区原则进行了研究,从电网分区运行方式、电网供电能力、分区转供能力与供电可靠性、大容量电厂接入220kV电网方案、无功电压配置与运行控制、正常频率运行等6个方面进行了探讨,以期对浙江电网的规划与运行提供一定的参考。

In this paper, the hierarchical and regional principles as well as the power network structure of Zhejiang power grid are researched based on the practical operation of Zhejiang power grid and experiences from home and abroad. Research are carried out in the following 6 aspects： hierarchical and regional principle, power supply ability, power transfer ability, power supply reliability, access of large capacity power plant to 220 kV power grid, configuration and operation control of voltage and reactive power, control of power system frequency, etc. Works done in this paper will be beneficial to power planning and operation of Zhejiang power grid in the near future.
