重载自动起机以及负荷分配试验 Test of 85%load depend on start 一台发电机运行,另一台发电机作为备用机。增加负荷至发电机功率的85%以上20秒后,备用发电机自动起,ACB自动合闸,负荷自动分配。两台发电机并联运行供电。 One DG running and connects,The others is standby. Increase the load more than 85% capacity of DG for 20 seconds, standby DG auto start and ACB connect. Load sharing automatically. Two DGs run in parallel and feed power. 具体见下表: See below table: 序号 No. | 准备 Preparative | 操作及观察 Operation & monitoring | 结果 Result | 1.
| #1发电机运行供电,#2发电机作备用机 DG1 is running and connect with MSB. DG2 is standby. | 增加负荷至85%以上20秒后,#2发电机自动起,ACB自动合闸,负荷自动平均分配。两台发电机并联运行供电。 Increase the load more than 1040*85%=884kW for 20 seconds, DG2 auto start and ACB connect. Load sharing automatically.

轻载自动减机试验 Test of 70%load depend on stop 两台发电机并联运行,其中一台作为备用机。当总负荷降低至单机额定功率的70% 以下10分钟后,负荷自动转移到主用发电机。备用发电机ACB自动脱扣,备用发电机自动停。主用发电机单独运行供电。具体见下表: Two DGs run in parallel. One of them is standby. When the load reduce to 70% capacity of one DG for 10 minutes, the load auto changeover to main DG. ACB of standby DG disconnects and standby DG auto stop. Main DG runs and feed power. See below table: 序号 No. | 准备 Preparative | 操作及观察 Operation & monitoring | 结果 Result | 1.
| #1发电机与#2发电机并联运行供电,#2发电机作备用发电机 DG1 and DG2 are running in parallel and connect with MSB. DG2 to be as standby. | 当总负荷降低至单机额定功率的70% 以下10分钟后,负荷自动转移到#1发电机。#2发电机ACB自动脱扣,#2发电机自动停。#1发电机单独运行供电。 When the load reduce to 70% capacity of one DG for 10 minutes, the load auto shift to DG1. ACB of standby DG2 disconnectand DG2 auto stop. DG1 running and feed power. | | 2.
