摘要 针对2022年云南大规模新能源规划的投产需要,结合当前电网短路电流较高的突出问题,开展新能源规划投产前后短路电流的对比分析,研究新能源接入对短路点短路电流的具体影响,并对短路电流不满足安全运行要求的场站提出合理的限制措施,以保障新能源接入下的电网安全稳定运行。 In response to the commissioning needs of Yunnan’s large-scale new energy plan in 2022,the prominent question that short-circuit current is high in the current grid is combined in this paper,where comparative analysis of the short-circuit current before and after the planning production of the new energy is developed,and then the specific impact of new energy access on the short-circuit current of the short-circuit point is studied.Finally,this paper also proposes reasonable restriction measures for stations whose short-circuit current can not meet the requirements of safe operation to ensure the safe and stable operation of the power grid under the new energy connection.
