摘要
针对常规下灵敏度校验的缺陷,本文提出了一种基于故障录波数据的灵敏度校验方法,在此方法的基础上,以某供电公司长勺站等变电站为实例开发了一个保护灵敏度数据库支持系统。并针对莱芜市电网中多条110kv线路做了大量的实验,其实验结果充分证明了本方法的灵敏性和可靠性。因此,本文所得的结论对保护定值的灵敏度校验具有一定的参考价值。
Under the flaws for sensitivity of conventional check, this paper presents a method of sensitivity check based on the data validation recorder,basis on this method, Changshao station of laiwu power supply company as an example developed a support system to protect sensitive database. And done a lot of experiments against number of grid lines 110 kv in the Laiwu City , The experimental results fully demonstrated the sensitivity and reliability of this method, so, The conclusions of this paper has some reference value to the protection of the sensitivity calibration.
