|
摘要
光纤光栅在线张力监测系统中,开展在线张力监测与覆冰模拟试验对保证线路安全运行非常重要。应用理论计算与实际测量,分析温度、风速、覆冰及初伸长对张力的影响,表明温度为主要影响因素。实施覆冰模拟试验,计算得出系统平均误差为4.5%,数据缺失率为0.14%,可靠性及稳定性高。研制的在线张力监测系统符合智能电网在线监测系统和安全保障体系的要求。
With the speeding up of the smart grid construction,it sets a higher request to the security system of power grid.Therefore,the on-line tension monitoring system for transmission line emerged as the times require.Through analyzing the results of tension real-time monitoring and icing simulation test on test line of the on-line tension monitoring system,the error rate of the system is 4.55% and the data loss rate is 0.14%,it is concluded that the accuracy,reliability and stability of the system are very high,it conforms to the smart grid on-line monitoring system design requirements.These research results have laid a good technical foundation for the test scheme and engineering application of the system,and have better application and popularization value in the actual circuit.
