| 摘 要： | 用EMTP程序模拟计算分析了500 kV湘潭—云田同杆并架双回线路(湘云线)的感应电流、电压及对系统不平衡度的影响等,为线路接地开关选择提出依据。验算线路对系统不平衡度影响的结果表明,线路两端500kV母线最大负序电压不平衡度为0.636%,流入湘潭发电机侧的最大负序电流不平衡度为0.70%,湘云同杆双回线不换位造成的负序电流和电压不平衡度都在允许范围内,不会给系统运行带来危害。 |
| 关 键 词： | 同杆并架双回路 不平衡度 感应电流及电压 接地开关 EMTP程序 |

| Abstract: | Aiming at the 500 kV Xiangtan-Yuntian (Xiangyun Line) Common-tower double-transmission line's inductive current, inductive voltage and the influences on the power system imbalance degree, the simulation, calculation and analysis is made for the line with EMTP program in order to bring forward the principles of choosing the grounding switch. And the influences of this line on the system imbalance degree are also checked to insure the safety of power system operation. |
| Keywords: | common-tower double-transmission line imbalance degree inductive current and voltage grounding switch EMTP program |
