摘要
描述了电力自动化研究院开发的,集非自治非线性多则体系统运动稳定性的定量分析技术、面向对象的分布式并行处理平台和区域稳定控制装置为一体的在线预决策的暂态稳定控制系统。该系统在线跟踪系统工况,用EEAC提供的受控电力系统的稳定裕度指标,快速搜索对应于给定故障集的、满足一定系统稳定裕度值的、控制代价为最小的控制策略,定期刷新控制执行装置中的控制策略表,从而对电网发展变化、运行方式改变具有很强的自适应能力。
The development of modern power networks highlights the problem of stability. and the adaptability of on-linestability control systems is essential to the secure and economic operation of large power systems. This paper presents an online transient stability control system trial-produced by Nanjing Automation Research institute. which is the world's firstsystem that integrates a unique technique for the quantitative analysis of general motion stability into an object orienteddistributed parallel processing platform and a regional stability control device. The system follows the current power systemoperating point. performs on-line stability calculation for a specified set of fault scenarios by using the stability marginprovided by EEAC in order to obtain control decisions which make the system sufficiently stable at the minimum lost. andthen Periodically refreshes the decision table stored in the control device. Therefore the system is adaptive to the developmentand change of operation of power systems. The use of EEAC for the fast quantitative analysis of stability in the system is aleading-edge technology in power system stability control.
