Ventilation air methane power generation system based on double circuits and control method thereof

Abstract

The invention discloses a ventilation air methane power generation system based on double circuits and a control method thereof. The system comprises a grid connection point, a gas generator set, a reactive power compensation device and a central controller, the grid connection point, the gas generator set, the reactive power compensation device and a load are connected with a bus, the gas generator set is connected with a ventilation gas intake pipeline; the ventilation gas intake pipeline is provided with an intake manifold, an exhaust header pipe, a first exhaust pipe and a second exhaust pipe, which are mutually communicated, the intake manifold is communicated with the gas inlet of the gas generator set, the other end of the intake manifold is respectively communicated with the first exhaust pipe and the second exhaust pipe, the other ends of the first exhaust pipe and the second exhaust pipe are communicated with the exhaust header pipe, and a normally open valve D is arranged on the exhaust header pipe; a normally open valve B is arranged on the second exhaust pipe; and the system further comprises a gas storage device, the gas inlet and the gas outlet of the gas storage device are communicated through a pipeline, and the pipeline is communicated with the first exhaust pipe. The system improves the power factor and saves energy.

Description

technical field [0001] The invention belongs to the technical field of energy utilization, and in particular relates to a dual-pipeline-based exhaust gas power generation system and a control method thereof. Background technique [0002] The gas generator set can make full use of exhaust gas, reduce exhaust gas emissions and reduce environmental pollution while realizing comprehensive utilization of energy. It is an environmentally friendly and energy-saving form of power generation that can actively promote the development of clean production energy. Realize the integrated process of coal mining, gas extraction and power generation, and effectively improve the production level. [0003] In the context of increasingly strong demand for energy comprehensive utilization and environmental protection, the connection of gas generating sets will have broad development and application prospects. There may even be two-way changes, resulting in fluctuations in the power factor of th...

[0003] In the context of increasingly strong demand for comprehensive energy utilization and environmental protection, the connection of gas generating sets will have broad development and application prospects. There may even be two-way changes, resulting in fluctuations in the power factor of the grid-connected point, which is lower than the power factor assessment value of the grid company, causing certain fines
