摘要
安全稳定控制系统作为大型区域电力系统安全稳定运行的三道防线之一,已在全国各地大型电网中投入运行。近年来随着地方经济的快速发展,电力工业的发展也越来越快,地方电网也逐渐趋向复杂,逐渐形成以220kV为主电压等级的辐射型电网拓扑结构,因此地区电网对电力系统安全稳定运行的要求也逐步突出。为确保地区电网的安全稳定运行,杜绝地区电网的大面积停电事故,研究和开发安全稳定控制系统在地方电力系统中的应用就显得尤为重要。
本文首先从安全稳定控制原理的理论上分析就地稳定控制与区域稳定控制两种模型的不同特点。分析了江门电网安全稳定控制的旧模式在运行中存在的缺点,根据江门电网在南方电网西电东送中的地位,采用区域稳定控制技术、网络通信及最新的微机保护计算等方面的技术,通过设置分布式安稳装置及通信网络来构建江门电网区域稳定控制制系统(由500kV控制子站(江门)和6个220kV负荷执行子站及它们之间的通信网络构成),为江门电网的安全稳定运行提供高效可行的解决方案。
当输入广东电网的直流或交流电源线路发生故障时,或当江门电网内部发生较严重事故时,按广东电网控制策略表的要求,接收广东电网安全稳定控制系统的指令,结合江门电网可切负荷的灵敏度和分布情况,按预定策略执行稳控措施,执行切负荷。由江门控制子站接收罗洞主站切负荷的指令或直接发出指令,再由江门控制子站根据所管辖的6个执行子站可切负荷量向各执行子站发出切负荷的指令,由各执行子站实施切负荷减载,这样以牺牲部分负荷的方式,确保江门电网的安全稳定运行。
Stability control systems as one of the three defenses in a major regional power system, have been put into operation in large power grid around the country. With the rapid development of the local economy in recent years, the rapid development of power industry has also been faster and faster, the local power grid became complex, and has gradually formed a voltage level of 220kV-based radiation-type network topology, the security and stability in the regional power grid has been become more and more important. In order to ensure security and stability of the regional power grid, eliminate the large blackout of the regional power grid, development and application of stability control systems in the regional power system become more and more important.
In this paper, we analyze the different between the local stability control system and the regional stability control systems by the theoretical principles of security and stability control, analyze the old model of security and stability control in Jiangmen power system and its shortcomings in the operation, according to the position of this system in west to east of the south power grid, we use regional stability control technology, network communications and the latest microprocessor-based protection and other aspects of computing technology, distributed by setting device and a secure communications network to build a regional stability control system in this system which is composed of a 500kV substation (Jiangmen) and six 220kV executive sub-stations and networks of communication between them, to provide a efficient and feasible solution of security and stability in this system.
When the AC or DC power line input to Guangdong power grid has a fault tripping, or when a serious accident occur in this system, according to the control strategy table of Guangdong power grid, Jiangmen control sub-station receives commands of Guangdong power grid security and stability control system instruction, Combined with sensitivity and distribution of the load in J this system, to shed the loads according to the predetermined strategies. Jiangmen control sub-station can receive load-shedding commands from Luodong master or issue load-shedding commands directly according to the loads of its six executive sub-stations, and then the executive sub-stations carry out the load-shedding commands, so that ,at the expense of part load way, this system can operate safely and stably.
