随着云南电网的快速发展,电网结构日益复杂,交直流混联运行、主网电磁环网运行、无功平衡和电压调整困难、局部电网结构薄弱,可靠性差,其运行的复杂性逐步增加,加之冰雪凝冻、地震、泥石流、雷暴等灾害频发,电网安全运行风险较大。做好电网运行风险管控、强化电网事故应急处置、提高各级调度人员应急处置能力是预防电网大面积停电的重要手段。超前分析科学定级协同联动闭环管控——超前分析中长期电网运行风险。结合电网当前运行情况,配合开展电网中长期分析,提出规划、技改、三道防线建设急需项目,便于公司计划、基
With the rapid development of Yunnan Power Grid, the structure of the power grid is becoming increasingly complicated. The AC-DC hybrid operation, the operation of the electromagnetic network of the main network, reactive power balance and voltage adjustment are difficult. The local power grid has weak structure and poor reliability, and its operation complexity gradually increases. Coupled with the freezing of ice and snow, earthquakes, debris flows, thunderstorms and other disasters, the larger the risk of safe operation of power grids. It is an important means to prevent large-scale blackouts in power grids by doing a good job in controlling and controlling the risk of grid operation, strengthening the emergency treatment of power grid accidents, and improving the emergency handling ability of dispatchers at all levels. Advanced analysis Scientific grading Cooperative linkage Closed loop control - Advanced analysis of medium and long term power grid operation risk. Combined with the current operation of the power grid, in conjunction with carrying out medium- and long-term grid analysis, proposed planning, technical transformation, construction of three lines of defense urgently needed projects to facilitate the company’s plan
