面对分布式光伏电站建设的发展，从锦州市城市级分布式建筑光伏电站示范项目实例出发，介绍一种新型的分布式光伏共网应用新模式，进而介绍一种一体化多模态光伏逆变设备。这种不同于传统逆变器设备，除了提供即发即用的光伏逆变功能外，同时还能提供就地无功补偿和谐波补偿，甚至在没有光伏时作为专门的补偿设备而使用。就此新模式对配电网运行与控制保护所带来的影响也作了介绍。“,”With the development of distributed photovoltaic power station construction, from the example of Jinzhou city level distributed building integrated PV demonstration project, this paper introduces a new type of distributed PV application mode, namely the grid co-existence new mode, a. And then it introduces presents an integrated multi-modal PV inverter device. Thise divice differs from traditional inverter equipment, in addition toexcept for providing inverter functionality with the immediately spent of electricity generated, at the same time, providing supplying on on-spot reactive power and harmonic compensation, even as a special compensation device when there is no sunshine, thus affecting the operation, control and protection of the distribution network.
