光伏逆变器一致性评估方法及系统开发

Assessment method of PV inverter consistency and system development

光伏逆变器作为光伏发电系统的核心部件,其品质的好坏直接决定了光伏发电质量的好坏,直接影响光伏发电系统接入电网的安全可靠。为保证评估现场所用逆变器和通过型式试验样品品质的一致性,提出了一种光伏逆变器一致性验证的方法,并利用RT-LAB半实物虚拟仿真器构建了一套光伏逆变器一致性评估平台。文中介绍了该方法的原理和平台的构建,并进行了具体案例分析,验证了该方法的参考价值。

As the core component of the photovoltaic power generation system,the quality of photovoltaic inverter directly determines the quality of photovoltaic power generation,and directly affects the safety and reliability of photovoltaic power generation system access to the grid.A method for the consistency verification of photovoltaic inverters is proposed to evaluate the quality of field inverters and the quality of the sample through the type test.A set of consistency evaluation platform for photovoltaic inverter is constructed through using the RT-LAB semi physical virtual simulator.The principle of this method and the construction of the platform are introduced in this paper.Finally, a concrete case study is conducted,and the reference value of the method is verified.
