Problems solved by technology

[0002] In some special power supply occasions, it is often necessary for the generator set to cooperate with the mains to supply power to the load. When the mains fails, the generator set is used to supply power to the load. However, it takes about 8~12 hours for the generator set to run. Seconds, during this period, there is no power to the load, so the load will be forced to suspend operation. In some occasions where the load needs to be continuously operated, the load is forced to suspend operation and will cause a lot of damage. For this, a Zero-second switching system between generator set and mains

Abstract

The invention discloses a zero-second switching system for a generator set and mains supply. The zero-second switching system comprises a load, the mains supply, a generator set, energy storage equipment and a switching module, wherein the mains supply is connected with the load and is used for supplying power to the load; the generator set is connected with the load and used for supplying power to the load; the energy storage equipment is connected with the load, and the generator set is connected with the mains supply and used for supplying power to the load; and the switching module is connected with the load, the mains supply, the generator set and the energy storage equipment and is used for switching a power supply for supplying power to the load. The energy storage equipment is added between the generator set and the mains supply, when the mains supply breaks down, the energy storage equipment supplies power to the load until the generator set starts power supply, power supply interruption can be prevented, gapless switching of the power supply is achieved, and it is guaranteed that the load can operate all the time; and the operation cannot be forced to stop.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a zero-second switching system between a generator set and a commercial power supply. Background technique [0002] In some special power supply occasions, it is often necessary for the generator set to cooperate with the mains to supply power to the load. When the mains fails, the generator set is used to supply power to the load. However, it takes about 8~12 hours for the generator set to run. Seconds, during this period, there is no power to the load, so the load will be forced to suspend operation. In some occasions where the load needs to be continuously operated, the load is forced to suspend operation and will cause a lot of damage. For this, a The zero-second switching system between the generator set and the mains. Contents of the invention [0003] According to an embodiment of the present invention, a zero-second switching system between a generator set and a...
