摘要
现代电网的安全经济运行迫切要求对暂态功角稳定、暂态电压稳定和暂态电压跌落可接受性等进行全面的定量分析.扩展等面积准则(EEAC)理论为开发稳定性量化分析软件提供了坚实的基础.根据暂态安全的3个方面之间的关系,在EEAC理论基础上构思建立了暂态安全定量分析软件的框架.论述了暂态安全定量分析软件的整体设计思路,介绍了有关软件所用的定量分析技术和主要功能,实例表明这些软件能快速、定量地评估暂态功角稳定性和电压安全性,满足在线暂态功角稳定和电压安全分析的要求.
Comprehensive quantitative analyses for transient angle stability, transient voltage stability and transient voltage-dip acceptability are urgent requirements for security and economical operation of modern power systems. Extended equal-area criterion (EEAC) theory provides a solid foundation for developing quantitative analysis software of power system stability. Based on EEAC theory, a framework for the quantitative analysis software of transient security is founded. The software is conceived on the relationship among three aspects of transient security. The design principles of the software packet are discussed, and the quantitative technology and main functions related to the software are introduced. Moreover, real cases indicate that the software can quickly and quantitatively assess transient angle stability and transient voltage security, and meet the need of on-line transient angle stability and transient voltage security analysis.
