秀山电网潮流分析与运行优化策略

针对秀山电网的现状,对整个电网进行了潮流计算,结果发现：电网存在潮流分布不均的情况,部分变电站严重过载,变压器负载率达到100％,由此导致电网局部运行极不稳定.基于上述问题,提出了秀山电网的优化运行方案,通过采取负荷转移结合电网建设的方式来控制潮流的流向,使功率得到合理分配.结果表明,能够有效改善变压器重载及过载现象,提高了供电的可靠性,同时为秀山电网的进一步规划建设提供了参考.

Analysis of Power Flow and Strategy of Operation Optimization For Xiushan Grid

In view of the current situation of Xiushan power grid, we calculate the power flow of the entire grid, and found that the power flow uneven distribution in the grid has caused serious overload in some transformer substations, with the load rate reaching 100%, thus leading to the extreme instability of the local grid. To address the above issues, this paper proposes the an operation optimization scheme of Xiushan grid, which adopts the load transfer method in combination with grid constnlction to control the flow direction, so as to make the power distribution reasonable. The result shows that, this scheme can effectively improve the transformer heavy load and overload, enhance the reliability of power supply, and at the same time provides a reference for further planning and construction of Xiushan grid.
