摘要
离网型风光储系统运行过程中的电压和频率是否稳定是整个系统稳定运行的必要条件。以离网型风光储为载体对各分布式电源输出能力以及整体稳定性进行试验分析,验证在离网模式下系统是否能够保证用户供电的稳定性和可靠性。通过由3 k W的风力发电机、3 k W的光伏电池以及1 000 Ah的蓄电池组成的系统进行试验,测量系统在运行过程中不同负荷下的输出特性来检测系统是否稳定。试验结果表明在不同类型负荷情况下系统的输出特性维持稳定,可以满足用户在不同类型负荷下的正常使用。
Voltage and frequency stability is a necessary condition for stable operation of the whole system during Off-grid wind / PV /battery hybrid power system. This paper analyses each distributed power output capability and overall stability based on Off-grid wind /PV / battery hybrid power system,verifies that the network model in vitro system is able to ensure the stability and reliability of electricity supply to customer. The system composed by 3 k W wind turbine system,3 k W photovoltaic cells and 1 000 Ah battery. This method can detect whether the system stable by measuring system output characteristics under different loads. Experimental results show that the output characteristics of the system under different types of load remained stable,consumers can normally be used in different types of loads.
