摘要
研究了与不同送出电网相匹配的安全稳定控制系统方案及各方案下安控装置的主辅运原则。分析了单点大电源远距离输电、多电源跨区域输电以及地区小网通过联络线向主网送电等不同送出电网存在的突出稳定问题;指出了为保证安控措施的恰当性与经济性,不同电网对安控系统的差别要求。通过对安控方案在拓扑结构、通道组织、站间交互信息、故障决策算法等方面的对比说明,给出了送出电网各种典型的安控设计方案,并分析了不同方案不同的主辅运设置原则。针对安控系统运行管理模式,给各方案提出了厂站间装置接点信号交互、双套装置柜间数据交换等建议。
The paper studies two aspects,including the security and stability control programs matching for different transmission networks and the relevant devices’main and auxiliary operation configuration principles.Typical stability issues of three grids have been analyzed.The three grids include grid of single point big power long-distance transmission and grid of multiple power cross regional transmission and grid of small area providing power for main network via tie line.Different grids need different stability control systems to ensure the appropriateness and economy of security and stability control measure.Through contrasting several aspects of different stability control systems,including topological structure,channel organization,information exchange and fault decision algorithm,the paper gives several typical stability control system solutions and analyzes the main and auxiliary operation configuration principles of each solution.According to different management modes,the paper provides several suggestions,including device signal contactor interaction,cabinet data exchange of devices,etc.data exchange of devices,etc.
