摘要
通过分析、比较准同期并列的3种基本条件以及相应的微机监测原理,提出微机自动准同期装置设计方案.用MATLAB软件分别对存在压差、频差和相角差的情形进行并列仿真;对仿真结果进行对比分析,发现在双柴油发电机组并列时相角差对机组的影响最大.最后根据不同条件下合闸对机组影响的大小,提出双柴油发电机组准同期装置整定和配合的原则.
By analyzing three basic conditions and microprocessor control fundamental of quasi-synchronization paralleling,a proposal for microprocessor control automatic quasi-synchronization device was put forward.The generator paralleling was simulated using MATLAB when voltage amplitude,frequency and phase angle were different.The result showed phase angle difference was the most important condition when two generators were parallel by comparative analysis of simulation results.The setting and coordinating principle for two generators quasi-synchronization was proposed according to the effect of switching on double-diesel generators under different conditions.
