我国靠自主装备攻克太阳能、风力发电“脱网”难关中国南车株洲电力机车研究所有限公司10月12日宣布,他们研制的具有特殊“电压穿越”功能的光伏逆变器通过国家级技术认证。这一成果使我国能依靠自主装备攻克太阳能、风力发电“脱网”难关。这种高技术装备能在光伏或者风力发电站连接电网发生电压骤降故障时,发挥“低电压穿越”功能,支撑电网恢复运行或避免故障扩大。经过我国唯一具有对这一技术认证资格的南京国网电科院太阳能研发实验中心检测,光伏逆变器波形等各项指标及测试数据表现良好,已经于10月上旬顺利通过技术认证。
China’s independent equipment to capture solar energy, wind power “off network” difficult CSR China Zhuzhou Electric Locomotive Research Institute Co., Ltd. on October 12 announced that they developed a special “voltage through ” function of the photovoltaic inverter through the country Level technical certification. This achievement enables our country to rely on independent equipment to capture solar energy and wind power generation. This high-tech equipment can function as a “low-voltage ride-through” function in the event of a voltage dip in the connection of a photovoltaic or wind power plant to the grid, supporting the grid to resume operation or prevent failure from expanding. After China’s only qualification for this technology certification of Nanjing National Grid EPRI Solar R & D Experimental Center testing, photovoltaic inverter waveform and other indicators and test data performed well, already in early October passed the technical certification.
