Ventilated methane power generation-based comprehensive energy power supply system and control method thereof

Abstract

The invention discloses a ventilated methane power generation-based comprehensive energy power supply system, which comprises an external power grid and a methane power generation system, wherein the external power grid and the methane power generation system are respectively connected to a bus and are used for supplying electricity; the bus is also respectively connected with a load, an electric boiler and a reactive power compensation device; a power meter is arranged at the grid-connected part of the external power grid, and is connected with a central controller; the central controller is connected to the methane power generation system, the electric boiler and the reactive power compensation device; and a reactive power compensation device access switch is arranged between the reactive power compensation device and the bus. The invention further discloses a control method for the ventilated methane power generation-based comprehensive energy power supply system to provide the power supply system of integrating power factor information and system state information to uniformly coordinate the overall power supply system.

Description

technical field [0001] The invention belongs to the technical field of remote management and control of new energy power generation, and relates to a comprehensive energy power supply system based on exhaust gas power generation and a control method thereof. Background technique [0002] The gas generating set is a new type of power generation that can make full use of the exhaust gas. It realizes the comprehensive utilization of energy while reducing exhaust gas emissions and reducing environmental pollution. Due to the connection of the gas generating set, the power factor of its upper-level grid-connected point will fluctuate, and a fine will be incurred when it is lower than the power factor assessment value of the grid company. However, the existing gas power generation system in the domestic market has a relatively simple structure, and it is impossible to integrate the power factor information to coordinate the power supply status of the gas generator set, and it is i...

Due to the connection of the gas generator set, the power factor of its upper-level grid-connected point will fluctuate, and it will cause fines when it is lower than the power factor assessment value of the grid company

However, the structure of the existing gas power generation system in the domestic market is relatively single, and it is impossible to integrate the information of the power factor to coordinate the power supply status of the gas generator set, and it is impossible to give full play to the overall technical and economic advantages of the system.
