摘要
2013年江苏电网年度用电量首度超越广东跃居全国第一。随着社会用电负荷持续增长,电网结构日益复杂,并呈现出网格状和多环网结构,故障后快速选择电网恢复路径,实现精益化的恢复供电变得日益困难。从工程实际角度出发,提出了计及设备风险的故障后恢复供电在线决策方法,以解决调度工作中遇到的实际问题。最后通过实际的故障案例验证了该方法的正确性和有效性。
Electricity consumption in the Jiangsu power grid in 2013 exceeded the amount of the Guangdong power grid and ranked the first over the whole country. With the increasing growth of power load and the complexity of the power grid, it is more important and difficult to choose the supply restoration path rapidly and realize elaborate supply restoration. Targeting at practical power system operation, an online-decision method of power supply restoration considering equipment risk is proposed in this paper, so as to provide technical support to the dispatch operation in the Jiangsu power grid. The effectiveness and correctness of the method are verified by the analysis on a real fault case that happened in the Jiangsu power grid.
