三: 系統運行方式

Three: the system operating mode

A) 自動運行

A ) automatic operation

(1) 當柴油發電機組和主控制屏處於自動模式時,壹旦正常電源發生故

(1) when the diesel generating set and the main control panel in the automatic mode, once the normal power supply occurs so

障,在收到啟動信號 10秒內,發電機啟動,第壹臺 90%的額定電壓和頻率將通過發電機斷路器連接到應急母線。第二臺至第七臺自動同步啟動,並聯於主母線,分擔系統負載。每臺發電機允許 3 10秒鐘的啟動嘗試,每次啟動間隔 10秒鐘。當 3次啟動嘗試全部失敗後,起動超時閉鎖功能,發出啟動失敗報警。

Avoidance, after receiving a starting signal generator for 10 seconds, start, the first90% of the rated voltage and frequency will be through the generator circuit breaker is connected to the emergency bus. Second to seventh automatic synchronous initiation, parallel to the main bus-bar, sharing system load. Each generator allows 310seconds of starting the experiment, each time interval10 seconds. When the 3start attempt failed after all, starting overtime locking function, a boot failure alarm.

(2) 收到啟動信號 10秒內,其余發電機同步自動啟動,並聯於應急母線,閉合斷路器。

(2) receives the start signal for 10 seconds, the remaining generators automatically start, parallel to the emergency bus, closed circuit breaker.

(3) 當正常電源恢復後,ATS系統(客戶提供)經過可調整的時間延遲,自動將所有負荷切換回正常電源。發電機斷路器同時斷開,柴油機將在無負載情況下運行 0 5分鐘時間停機,時間可以通過控制屏調節。控制屏自動復位到待機狀態。

(3) when the normal power is restored, the ATS system ( customers ) after the adjustable delay time, automatically converts all load switching back to the normal power supply. Generator breaker opened at the same time, diesel engine will be under no load condition to run 0to 5minutes down, time can be achieved through the control panel control. Control panel automatic reset to standby state.

B) 手動運行

B ) manual operation

(1) 當主控制處於手動模式時,整個應急柴油發電機系統處於手動狀態,由柴油發電機選擇開關控制機組的啟動和停止。

(1) when the main control in manual mode, the emergency diesel generator system is under manual condition, by a diesel generator selector switch control unit start and stop.

(2) 保護功能在手動運行和自動運行時同樣有效。

(2) protection in manual operation and automatic operation is still valid.

C) 柴油發電機模式選擇

C ) diesel generator mode selection

每臺柴油發電機應具備以下運行模式:

Each diesel generator should have the following operation mode:

(1)緊急停止:當發電機運行時,無論什麽時候按下緊急停止按鈕,機組將立刻停機並且發電機斷路器將斷開。嚴重故障也可引起柴油機急停,閉鎖啟動功能,直到工作人員排除故障並復位閉鎖。
