摘　　要：充裕度是衡量电力系统可靠性和经济性的重要指标之一。随着电力系统规模的不断扩大和运行特征的日趋复杂,现有的一些简单而易于手工计算的充裕度指标已经越来越难以满足现代电力系统规划和运行的实际需要。在此背景下,针对广东电力系统调度的实际需要,首先确定了电力系统充裕度评估分析的研究框架,明确了需要研究的主要内容;之后,讨论了软件实现的总体原则和基本思路;最后,基于Microsoft Visual Studio 2005平台和结构化查询语言Microsoft SQL(structured query language)Server 2000数据库实现了电力系统充裕度评估分析软件系统,主要包括发电容量充裕度分析、电力网络供电脆弱性评估和系统单元充裕度计算3个功能模块。将所开发的软件系统应用于广东电力系统,证明了其有效性。Power system adequacy represents an important index for evaluating the reliability and economy of a power system. With the development of modem power systems and ever-increasing complexity of power system operation, the existing power system adequacy analysis framework can not meet the requirements of power system planning and oper- ation. Given this background, a new adequacy assessment framework is first developed with the actual needs of Guang- dong power system dispatching taken into account. Then, a software system is developed based on the Microsoft Visual Studio 2005 platform and Microsoft SQL（structured query language） Server 2000 database. The software system can be divided into three major modules which are generation capacity adequacy analysis, power supply vulnerability assess- ment and module adequacy assessment. Finally, the feasibility and efficiency of the developed models, algorithms as well as the software system are demonstrated by the simulation results of the Guangdong power system.
