同期装置测试设备及测试方法

Test equipment and test methods for synchronization devices

为了满足发电厂和变电所对同期装置测试的要求,特别是对微机型同期装置的测试,分析测试过程中存在的问题,提出了对测试设备的要求并介绍了测试方法。包括两侧电压存在幅值和相位差时的校正,电压闭锁值、频率闭锁值、导前时间、导前角、电气零点、调频脉宽、调压脉宽的测试,动态模拟实际并网情况的调整试验。

To meet the requirements of power plants and substations for the test of synchronization devices,especially the digital synchronization devices,the problems in test are analyzed,the require-ments on test equipment and test methods are introduced.The study covers the calibration when the voltages of two sides differ in both amplitude and phase,the measurement of voltage closedown value,frequency closedown value,leading time ,leading angle,electrical zero,frequency-modulated pulse-width,voltage-modulated pulse-width,etc.and the adjustment test under the dynamically simu-lated network-paralleling situation.
