摘要
本文对广东江门新会IGCC发电实验平台配套的接入系统方案对电网保护的影响进行了详细的分析研究,由于本平台容量(120MW)在110k V电源中相对较大,其助增作用会引起的阻抗变化和保护范围的变化,故对根据现有运行设备的实际情况,并依据广东电网公司继电保护及相关规程的要求,从各级保护的配合、灵敏度的选择、运行方式选择等方面进行了分析,科学地配置设备,得出可行的方案。
Effects of access system based on Guangdong Jiangmen Xinhui IGCC power generation experiment platform supporting on power system protection are analyzed in detail, Because the platform capacity（120MW） in the 110 k V power is relatively large, the change of impedance change and the scope of protection of the infeeds effect will be caused, so based on the actual situation of existing operation of equipment, and based on the rules and the relevant requirements of the relay of the Guangdong Grid Co, was analyzed from the aspects of cooperation at all levels, the sensitivity of the protection, the choice of selection of operating mode, the scientific arrangement of equipment, gives the feasible scheme.
