Power supply adjusting system and power supply adjusting method

Abstract

The invention discloses a power supply adjusting system which comprises a power supply side bus, a power utilization side bus, a change-over switch, a fuel generator set and an energy storage device,an external mains supply is connected to the power supply side bus, and an external load connected to the power utilization side bus. The change-over switch is arranged between the power supply side bus and the power utilization side bus, one end of the change-over switch is connected with the power supply side bus, the other end of the change-over switch is connected with the power utilization side bus, and the energy storage device is connected into the power utilization side bus. The invention further provides a power supply adjusting method. The method is based on the power supply adjusting system. By adopting the power supply adjusting method, the power supply adjusting system can be conveniently applied to emergency power supply occasions and the condition of unbalanced power supplyand load, and has the beneficial effects of realizing uninterrupted power supply, improving the energy utilization rate of the system, reducing the kilowatt-hour energy consumption, improving the working efficiency, avoiding delay of the construction period due to expansion application and the like.

Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to a power supply regulating system and a power supply regulating method thereof. Background technique [0002] Modern society is increasingly dependent on electricity. The supply and demand relationship between the city power supply and the power load is greatly affected by factors such as power consumption area, power consumption time period, power consumption nature, unexpected accidents, and power transmission. It happens from time to time that the power supply is cut off or the power supplied by the mains cannot meet the needs of the load. How to deal with the above-mentioned emergencies, balance the power supplied by the power supply side and the power used by the power consumption side, so that it can maintain an overall balance, is a technology in the art. Technical issues that personnel need to solve urgently. [0003] Aiming at the situation of sudden i...

Problems solved by technology

[0006] It should be pointed out that when a diesel generator is applied to an emergency power supply occasion, the diesel generator itself will have serious defects: on the one hand, if the diesel generator is kept on and waiting for emergency power supply, the diesel generator will always generate fuel consumption and waste energy. Serious; on the other hand, if the diesel generator is always off and only starts to supply power to the load when the mains power supply is cut off, its startup process will generally take tens of seconds or even minutes, and the load will experience power supply during its startup process. gap

[0007] In addition to the above-mentioned situation of sudden interruption of mains power supply, power users generally face the problem of unbalanced supply and demand between mains power supply and power load. demand; or the load experiences low power consumption, and the mains supply is oversupplied; if the mains supply is insufficient, the power consumer needs the power supply department to apply for capacity expansion, and the application for temporary capacity of the mains is easy to be restricted, and the approval period is generally long. It is unrealistic for power consumers who are in urgent need of electricity
