多台发电机如何并网？船舶发电机并车    

需要安装同期并网装置，

    并网的四个条件：

    1. 多台发电机的频率相同。

    2. 多台发电机出口电压相同,其最大误差应在5%以内。 

    3. 多台发电机相序相同。

    4. 多台发电机相位一致。

500kw发电机与市电并机注意事项

发电机组并网运行有几个技术条件：1.可再生能源发电且装机功率大于500kW，国家是鼓励并网发电的。如果是柴油发电机组或者是单机装机功率小于500kW，一般是不能办理并网发电手续的。
2.并网发电机组必须配备自动同期检测装置（检测电压、频率、相序）及逆功率保护装置（避免反送电），还有电力部门要求的线路保护等其他保护条件，电力调度专线、及经过培训的电力调度操作人员。

双路电源自动转换电路，双电源电路遇到停电是否会自动切换? 

自动切换装置有：双电源自动切换开关（ATS)、接触器。
双电源切换开关有很多种有ATS/CTTS/DTTS/ATB/ACTB/STS/SLTS/MVATS/MVCTTS。
常用低压的双电源自动切换开关有PC级的和CB级的。PC级的采用励磁驱动，一体式机构，具有切换时间快 安全可靠，切换时间在100-300毫秒。CB级是用两个断路器为基础，切换时间在2000-3000毫秒。

How many generator hooked up? Marine generator and car

Need to install the interconnection device during this period,

Interconnection of the four conditions:

1. The more the frequency of the generator is the same.

2. More than export voltage generator is the same, the maximum error should be within 5%.

3. The generator phase sequence is the same.

4. Many sets of generator in phase.

500 kw generator and mains weaver matters needing attention

Generating unit parallel operation are a few technical conditions: 1. Renewable energy power generation and installed power more than 500 kw, countries is to encourage the grid-connected power generation. If the diesel generator set or single machine installed power less than 500 kw, the general is can't go through the formalities of the grid-connected power generation.

2. Parallel generating unit must be equipped with automatic detection devices (detection voltage, frequency, phase sequence) and reverse power protection device (to avoid the transmission), and line protection and other protection conditions required by the power sector, power dispatching of electric power dispatching dedicated and trained operators.

Double circuit power supply automatically switching circuit, the double power supply automatically switching circuit in a power outage?

Automatic switching device are: dual power automatic transfer switch (ATS), the contactor.

Dual power supplies switch there are many kinds of ATS/CTTS DTTS/ATB/ACTB/STS/SLTS/MVATS/MVCTTS.

Commonly used low pressure double power source automatic switch are PC grade level and CB. PC level driven by excitation, one-piece body, has the fast switch time safe and reliable, switch time from 100 to 300 milliseconds. CB level is to use two circuit breaker, switch time from 2000 to 3000 milliseconds.
