粤东电网稳控系统改造的功能设计及其运行控制

The Functional Design and Operation Control of Reconstructive Security Stability Control system for Eastern Guangdong Power Grid

基于粤东电网在新的运行工况下可能存在的各种严重故障分析,考虑到系统安全稳定控制需要和稳控系统工程实施情况,提出了本期粤东稳控系统的改造和配置方案,结合实际控制手段完善了切机分配方法。分析了对粤东送出断面稳定性影响较大的薄弱环节,建议在实际运行控制中应做好事前控制和事后控制,以切实保证粤东电网的安全稳定运行。

Based on the analysis of possible critical faults of Eastern Guangdong Power Grid （EGG） under new operation conditions, and considering the demand of security-stability control system and its practical progress, a reconstruction and configuration scheme of EGG security stability control system is proposed, improving the generation-shedding distribution method with practical control means. Furthermore, several aspects of weakness of EGG sending cross-sections with great impacts on stability are analyzed, suggesting practical pre-control and post-control operations to insure the EGG security and stability
