摘　　要：结合2012年国家电网开展了并网机组网源协调专项核查工作,发现670 MW机组均存在发电机组转子过负荷综合能力、调差系数定值不满足相关国家标准和行业标准的要求,机组辅机系统相关保护存在误动。针对这些问题展开整改并提出解决方案,保障电网的安全稳定运行。In combination of special verification of grid-connected units net source coordination carried out by State Grid in 2012,it is found out that problems existed in 670 MW grid-connected units such as rota overload and the differerntial coefficient of fixed value,which could not meet the requirements of relevant national standards and industry standards. Also malfunctions occured to auxiliary system protection. Countermeasures are proposed to ensure safe and stable operation of the system.
