摘要
保证电力系统的安全稳定运行是人们极为重视的问题。防止系统暂态稳定破坏的控制仍然是当前电力系统中极为迫切的任务。
     目前稳定控制装置主要是应用简化的判据,或采用查询离线计算策略表方法构成的局部稳定控制。因此策略表在电力系统稳定控制中仍将起重要作用。通过制定安全稳定策略表,在运行中下传各项指令以达到控制电网稳定的功能。
     本文分析了电网安全稳定控制系统的结构模型,对电网安全稳定控制系统的研究方案做了较为深入的探讨,对其决策表的录入接口程序和决策表的存储结构进行了较为深入的研究.
     结合实际电网安全稳定装置的组成部分,了解安全稳定控制系统的实际情况是必不可少的过程。本文的第二章分析安全稳定控制系统的类型,特别是对主站的功能模块做了介绍。
     如何在电力系统中实行安全稳定控制是本文研究的重点,那么必须讨论安全稳定控制系统的决策问题。本文的第三章将就各种决策方式进行总结,并说明决策表的形成原理和程序要求。
     安全稳定控制系统的离线决策表需要输入到控制系统中,并由控制系统根据实际运行情况传送到相应的执行机构执行。本文的第四章结合实际分析决策表录入问题,提出设计思想,从而设计决策表接口程序。
To assure the power system to run stably and securely is a very important problem to people. Nowadays,the control to prevent the transient stability of power system from being destructed is still a very exigent task.
    At present,predigested criterions,or local stabilization controls with the Cure Table accounted offline,are applied to stability control facility. So the Cure Table still plays an important role in the power system stability control. By designing the Cure Table of local stabilization control and transmitting each dictate,we can actualize the control of power system.
    The thesis analyzes the structure of the stability and security of electric power net,discusses the research project,designs the control program and argues the memory frame.
    By associating the actual parts of equipments,the stability and security of power system will be found out clearly. Chapter 2 of this thesis analyzes the types of power system,specifically introducing the function module of the main station. The major part of this thesis is researched to control the stability of the power system,so discussing the decision-making is essential. Chapter 3 of this thesis summarizes the form of decision-making and explains the principle and demand of program.
    The offline Cure Table must be inputted to the controllable system,and be transmitted to the executive equipment by the program according to the actual things. Chapter 4 of this thesis analyzes the quest ion of Cure Table actually,brings forward the idea of program and designs it.
