本文介绍了自动电网动态参数检测仪能够在三个周波(60ms)的时间内检测电网上的三相电压、电流有效值、三相功率因数和频率,计算出相应的三相有功功率、无功功率。当电网参数发生5种情况的异常现象时,打印机将打印出发生异常时刻前后5s(178点测量值)的测量值和发生异常时刻的时间。在电网参数正常情况下,可以任意设定定时打印时间(5min～95min),打印机在定时时间到时刻打印出该时刻的年、月、日、星期、时、分、秒和检测到的16个测量值。显示器能够轮流显示所测的16个值。
This paper introduces the automatic grid dynamic parameter detector can detect the three-phase voltage, current RMS, three-phase power factor and frequency in three weeks (60ms) time, calculate the corresponding three-phase active power, reactive power power. When there are 5 cases of anomalies in the grid parameters, the printer will print the measured values 5s (178 points measured) before and after the occurrence of the abnormal moment and the time when the abnormal moment occurred. Under the condition of normal grid parameters, the timing printing time (5min ~ 95min) can be arbitrarily set. The printer prints out the year, month, day, week, hour, minute and second of the time at the time and the detected 16 Measurements. The display can take turns displaying the measured 16 values.
