Problems solved by technology
The power system of this power receiving method is stable and reliable, and has sufficient capacity, but the workload in the early stage is large and the construction period is long. Therefore, in order to shorten the construction period and save construction costs, the temporary power receiving method of the plant system can be used for plant power reception. Entering the stage of monomer debugging and sub-system debugging, and in the process of temporarily receiving electricity for the factory system, due to the randomness of the temporary power system, its capacity often cannot meet the requirements of the trial operation of the component system of the newly built machine. Therefore, it is necessary to look for a multi-power supply Parallel factory power supply system and its parallel method are of great significance

The invention discloses a multi-power parallel plant power supply system and a parallel method thereof, comprising a No. 1 unit diesel generator unit, a No. 1 unit security section unit, a No. 2 unit diesel generator unit, a No. 2 unit security section unit, Low-voltage factory-used bus unit, low-voltage factory-used transformer, high-voltage factory-used bus unit, high-voltage factory-used temporary power supply and parallel devices; the diesel generator unit of No. The diesel generator unit of No. 2 unit is connected with the low-voltage service bus unit through the security section unit of No. 2 unit, and the low-voltage plant bus unit is connected with the high-voltage plant temporary power supply through the low-voltage plant transformer and the high-voltage plant bus unit. The low-voltage plants are connected with busbar units, and the system and method can effectively reduce the workload in the early stage, shorten the construction period, and reduce the construction cost.
Description
technical field [0001] The invention belongs to the technical field of electric power debugging and electric power testing, and relates to a multi-power parallel type factory power supply system and a parallel method thereof. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, the society's demand for electricity is increasing day by day, and the number of new generator sets is increasing. [0003] In the process of building a new generator set, the current phase of the project's booster station and the reverse power transmission method of the start-up and standby transformers are usually used to receive power for the plant system, and then the individual systems of the generator set are commissioned and the sub-systems are tested. The power supply system of this power receiving method is stable and reliable, and has sufficient capacity, but the workload in the early stage is large and ...
