摘要
为简化计算常将电力系统不需要进行详细分析的某些区域进行等值简化.以典型算例和实际大规模区域电网为对象,对PSASP中的EPRI E'动态等值功能进行验证分析,指出其优点和不足.该功能操作简便实用;既可用于单区域等值,也可以实现多区域等值;既可用于稳态等值计算,也可实现机电暂态稳定等值计算;但在某些情况下可能出现无法完成等值计算即等值失效的情况,具体原因及其改进措施有待进一步研究.
For simplified calculation, we often simplify some areas that do not need intensive study in power system analysis. By using the PSASP software to process dynamical equivalence calculation in typical example and actual large scale power networks, this paper analyzes the advantages and disadvantages of PSASP dynam ical equivalence function, which is named EPRI . It is convenient to use. It could calculate multiple equiva lence and the calculated results are suitable for transient analysis. But in some situations the EPRI equivalent can not get results, and the equivalent calculation interrupts. The specific causes and improvement measures need to be further studied.
