应急发电机试验手册(正式)资料

记录各有关参数.Check and record the concerned parameters

注：在负荷试验后立即测量热态绝缘电阻。进行上述各项试验时，应检查滑油、冷却水排气等各有关参数是否符合要求，各运动部件是否有不正常现象。

Noted: After load testing, should measure the hot insulation resistant immediately, .During the above testing checks the relational parameters of L.O,cooling water,and exhaust gas temperature .

2.4 应急发电机组调速器和瞬态调压特性试验。

Emergency D/G set governor and momentary characteristic test

当发电机在全负荷状态运行时，突然将负荷全部卸去，即（100%→0%），检查柴油机转速的变化情况和稳定所需的时间，然后，突加上100%的负荷，进行观察，即（0→100%）进行1次。

要求：最大允许瞬时速降：≤10%

稳定调速率：≤5%

稳定时间：≤5秒

记录柴油机的瞬时转速、稳定转速以及稳定时间。

When the generator is unloaded suddenly from 100% to 0%（100%→0%）, measure its momentary speed and steady speed, record the time.

When the generator is loaded suddenly from 0 to 100%（0→100%）, tmeasure its momentary speed and steady speed, record the time.

Requirements：Max. Permit Momentary speed rate ≤10%

Steady speed rate ≤5%

Steady time ≤5 seconds(steady time means the time when the speed returns to the range within 1% of final steady speed.)

2.5 应急发电机稳态调压特性试验Voltage characteristic test

在额定负荷下，将电压和频率调至额定值，然后按顺序

100%→75%→50%→25%→0→25%→50%→75%→100%改变负荷，同时测量各负荷点的电压和频率等。

Running at 0%, 25%, 50%, 75%, 100% rated load separately, record the frequency the voltage and the current value after stable.The result of test should be recorded.
