| 摘要: |
| 结合电力网的实际结构及运行特点,利用定值判断法,采用面向对象的程序设计思想开发了基于图形界面的电网继电保护动作仿真系统.该系统可模拟电网在实际故障中的保护动作情况,通过调用故障计算模块得到故障下各保护处测量值,与系统保护整定值进行比较判断,得到保护仿真结果,实现对全网保护整定值的校验.提出了面向装置的距离保护整定值校验思想,保证了保护动作仿真功能的正确性和有效性.该系统通用性好、使用灵活,具有较大的实用价值. |

| Abstract: |
| Combined with the actual structure and operating features of electric power system,a graphic action simulation system of relay protection is developed,which applies fixed value estimation method and object-oriented technique. The system simulates protective actions on actual faults. Measurements at each fault protection point are derived with fault calculation module,which are compared with setting values of system protections for system-wide verification. An equipment-oriented setting value verification method is put forward for distance protection,which ensures the correctness and effectiveness of protective action simulation. The system is versatile,flexible and practicable. |
