Then the load test, selection of host, starting the engine, transmission, load to about 80%, preparing the machine should start, automatic machine, automatic distribution of load. When decreasing the load of less than 35%, preparing the machine should be out of shutdown.

五、使用操作

Five, the use of operation

(一):自动并机运行: 1 、启动、并机:启动发电机组,合上发电机组的空气开关(如有的话),送电至并机柜,调节频率和电压使 2 台机组电压一致(不超过 5V )和频率一致(不超过 0.1Hz )。 30 秒内机组应自动并机,并机成功后,把并机选择开关扭到 0 档。 2 、解列:当负荷降至 35% 以下,可按备用机组的分闸按钮解列,空机运行 3 — 5 分种后停机,另 1 台机组可单机运行或分闸停机。 3 、故障停机:当机组出现高水温、低油压等故障信号送至并机柜,使并机柜解列,故障指示灯亮。这时负荷会加至另 1 台机组上,如负荷过大将导致运行的机组停机。出现故障停机,应立即减小负荷至 1 台机组能承担的范围。出现故障停机并查明原因后再投入运行。

( a ): automatic and machine operation:1, priming, and machine: starting generator, closed turbine air switch ( if any ), transmission to and cabinets, adjusts the frequency and voltage to2voltage consistent units ( not more than 5V) and frequency ( less than 0.1Hz ). 30 seconds set should be automatically and machine, and after the success of the machine, and machine selection switch to0 archives. In 2, splitting: when the load is reduced to below 35%, according to the standby unit brake button series, an empty machine running3- 5 minutes after shutdown, the other1 units can be stand-alone or gate stop. 3, breakdown: when the unit is high temperature, low oil pressure fault signal is sent to and cabinets, and cabinets series, fault indicator light. When the load will increase to1 units, such as load will lead to operational units shutdown. Fault shutdown, should immediately load is reduced to 1units can afford. Failure stop and identify the cause and then put into operation.

4 、紧急停机: 2 台机组并机运行出现较大环流,且又不能消除时,应分闸解列。电流、电压、频率波动较大时,可按急停按钮解列和停机。

4, emergency stop:2 units and machine running large circulation, and can not eliminate, should switch series. Current, voltage, frequency fluctuation, can press the emergency stop button out and stop.

(二):调峰运行:选定主机,启动主机,送电,带负荷,主机组根据负荷大小决定并机或单机运行。

( two): peaking operation: selected host, starting the engine, transmission, load, the host group according to the load size and machine or stand-alone operation。
