摘要
Abstract
Based on online stability control decision-making technology, the on-line pre-decision system of China southern grid is developed, which is a combination of power system stability analysis, stability judging, fault pre-warning and control calculation. The system achieves the functions such as steady stability, transient stability, dynamic stability analysis and refreshing the control strategy in stability control devices. The hardware of the system is composed of database server, computation servers, Web server,monitoring and maintaining terminals, disc array, communication device, firewall, physical isolation device, communication machine,and stability control device. All analysis program is developed in C++ language, and it can support Windows and multiple types of Unix. Multi-thread algorithm, distributed computation and early termination technology are adopted to ensure the online computation speed, and the computation precision is demonstrated by comparing with the BPA transient stability computation programme.关键词
