GE DS2020EXPSG3电源励磁机
3ΦNEG REACT ENERGY:此消息显示自上次重置时间日期起的负varhours（单位：kvarh）。负方向的无功功率将增加该累积值，而正方向的无功率将增加正无功小时值。S1 PQM SETUP\CLEAR DATA\CLEAR ENERGY VALUES设置点清除该值。一旦达到值4294967295（FFFFFFFF h），显示的值将滚动到0。3Φ表观能量：此消息显示自上次重置时间日期以来的累计VAhours（单位：kVAh）。设置点S1 PQM SETUP\CLEAR DATA\CLEAR ENERGY VALUES清除该值。一旦达到值4294967295（FFFFFFFF h），显示的值将滚动到0。REAL ENERGY LAST 24小时：此消息显示过去24小时内累积的实际能量（单位：kWh）。当施加控制电源时，PQM使用的24小时周期开始。PQM根据之前的24小时周期每小时更新一次该值。如果PQM的控制电源断开，该信息将丢失。
3Φ NEG REACT ENERGY: This message displays the negative varhours (in kvarh) since the TIME OF LAST RESET date. Reactive power in the negative direction will add to this accumulated value, and reactive power in the positive direction will add to the positive varhour value. The S1 PQM SETUP \ CLEAR DATA \ CLEAR ENERGY VALUES setpoint clears this value. The displayed value will roll over to 0 once the value 4294967295 (FFFFFFFFh) has been reached. 3Φ APPARENT ENERGY: This message displays the accumulated VAhours (in kVAh) since the TIME OF LAST RESET date. The setpoint S1 PQM SETUP \ CLEAR DATA \ CLEAR ENERGY VALUES clears this value. The displayed value will roll over to 0 once the value 4294967295 (FFFFFFFFh) has been reached. REAL ENERGY LAST 24h: This message displays the accumulated real energy (in kWh) over the last 24-hour period. The 24-hour period used by the PQM is started when control power is applied. The PQM updates this value every hour based on the previous 24-hour period. This information will be lost if control power to the PQM is removed.
