【摘要】 <正> 电力系统的安全运行是四化建设的关键。目前,国内各电力网对其动稳定破坏和静稳定破坏问题不但不能预测,甚至还没有一种合适的装置去反映电网的本质。功角监测装置可以监视电网的电势或母线电压之间的功角摆开情况,借助这种装置可以观察电网的运行情况及状态,当运行异常时,装置自动发出告警信息,有利于排除电网的静稳定破坏。而电网的动稳定破坏问题从发生到破坏仅仅只有几分钟不易排除,本装置能自动记录破坏过程中的功角变化情况,对事故的分析极为有利。我们所研制的监测装置在我省东部电网局部地段进行了现场调试和试用,取得了初步验证。更多还原

【Abstract】 Power angle monitor and measuring equipment is an important equipment for monitoring and measuring the stability of a power system. This equipment provides digital display of the relative power angle between any two of six measurements, compares automatially the first measured point with the last one and displays the results with characters. When the power angle exceeds the first set value, the light and sound warning will be given. When the power angle exceeds the second set value, the wave recorder will automatically start to record the variation of the power angle during the failure process.更多还原
