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):自動并機運行: 1 、啟動、并機:啟動發電機組,合上發電機組的空氣開關(如有的話),送電至并機柜,調節頻率和電壓使 2 臺機組電壓一致(不超過 5V )和頻率一致(不超過 0.1Hz )。 30 秒內機組應自動并機,并機成功后,把并機選擇開關扭到 0 檔。 2 、解列:當負荷降至 35% 以下,可按備用機組的分閘按鈕解列,空機運行 3 — 5 分種后停機,另 1 臺機組可單機運行或分閘停機。 3 、故障停機:當機組出現高水溫、低油壓等故障信號送至并機柜,使并機柜解列,故障指示燈亮。這時負荷會加至另 1 臺機組上,如負荷過大將導致運行的機組停機。出現故障停機,應立即減小負荷至 1 臺機組能承擔的范圍。出現故障停機并查明原因后再投入運行。

( 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 、緊急停機: 2 臺機組并機運行出現較大環流,且又不能消除時,應分閘解列。電流、電壓、頻率波動較大時,可按急停按鈕解列和停機。

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):調峰運行:選定主機,啟動主機,送電,帶負荷,主機組根據負荷大小決定并機或單機運行。

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