摘　　要：针对分布式光伏电站中组串逆变器数量较多、布置分散给电站功率调节带来的问题,提出了一种区域智能调控系统。采用分层控制的调节方式,将光伏监控主站的功率调节任务按照一定的分配算法分配给多个区域智能调控单元,各智能调控单元同时调节完成整个光伏电站的功率调节任务并实时上送至监控主站。该系统在减轻监控主站调节负担的同时可大大提高调节速度及调节精度,具有广泛的工程应用价值。To solve the problem of power condition in distributed PV station with numbers of serial and disperse arranged inverters, a regional intelligent regulating system is proposed. The new method assigns the adjustment command of PV monitoring main substation to different intelligent with an allocation algorithm by adopting hierarchical control regulation way, then all intelligent regulating units adjust at the same time to achieve the power regulation of the entire PV station and send the power to the master station. This system can reduce the burden of master station and improve the regulative speed and precision effectively, which has good practical value for distributed PV station.
