Solar energy is loved and developed by various countries as a green energy source. Solar energy sources have been widely used in many developed regions, and wind energy and solar energy are being actively developed and used in China. We are striving to apply these new energy sources to our production and life. At present, we can It is applied to solar photovoltaic power generation in many aspects.

After the solar photovoltaic power generation system is tested, it can enter the staged debugging and trial operation links. During the commissioning operation, it is necessary to strictly follow the relevant specifications and design requirements, carefully check and test each step of the operation, and ensure that all the Hidden problems, pay attention to personal safety issues during the debugging process, and be organized. The following is an example to explain:

Grid-connected commissioning phase of solar photovoltaic power generation system

The first is the sequence of power supply operations: closing, power failure, power debugging

Close the switch of the upper array mixing box, check all the DC input voltages of the DC power distribution cabinet, check whether the voltage power supply is input, close the low-side switch of the box transformer, close the inverter auxiliary power switch, and close the inverter DC input switch of inverter, close DC switch output switch, close inverter output AC switch

Segmented inverter output AC switch, segmented inverter DC input switch, segmented DC power distribution cabinet output switch, segmented inverter auxiliary power switch, segmented box low voltage side switch

Power transmission debugging includes: high voltage power transmission debugging, power transmission to the transformer and impact test, DC system and inverter system on-grid debugging, etc.
