摘 要: 當(dāng)并網(wǎng)逆變器的輸出與負(fù)載需求的功率相匹配時,被動式孤島檢測方法就會失效。介紹了帶正反饋的有源頻率偏移法檢測孤島效應(yīng)的原理,討論了該法可能存在的檢測盲區(qū),并基于此法在Matlab/Simulink 平臺進(jìn)行了系統(tǒng)的仿真驗證。結(jié)果表明,該法檢測孤島效應(yīng)迅速有效,對特定負(fù)載無檢測盲區(qū),達(dá)到了孤島檢測相關(guān)標(biāo)準(zhǔn)的要求。

Abstract: When the grid-connected inverter output power was equivalent to the power of loads, the passive islanding test might be ineffective. Introduction was made to the principle of active frequency drift (AFD) method with positive feedback to test islanding effect. This paper discussed the possible blind zone by AFD method and based on this method, simulation verification was carried out on Matlab/Simulink platform. The results show that the method to test islanding effect is fast and valid, without test blind zone for special load, to have reached requirements of related islanding test standard.
Key words: islanding test; photovoltaic; grid-connected inverter; active frequency drift method
