Natural gas distributed energy optimization system

Abstract

The invention relates to a natural gas distributed energy optimization system, which includes a gas generator set, a boiler system, a power grid system, a power supply network, a waste heat recovery device, a load detection unit and a master control terminal; the gas generator set and the boiler system are composed of the same combustion chamber The gas heat source is provided, and the boiler system is used for user heating; the gas generator set is connected to the power supply network, and supplies power to the user terminal through the power supply network, and the waste heat generated by the gas generator set is recovered by the waste heat recovery device for the user's heating load; The real-time load at the end and the peak value prediction of the grid system adjust the heat source supply of the combustion chamber to the gas generator set and the boiler system, and at the same time adjust the power supply of the gas generator set and the grid system. This plan connects the gas generator set to the national grid. At the same time, by introducing a reasonable control mechanism, the problem of single power generation and large energy loss of a single gas generator set is also reduced.

Description

technical field [0001] The invention relates to the field of natural gas, in particular to a natural gas distributed energy optimization system. Background technique [0002] Natural gas distributed energy has a history of more than 30 years abroad, and has developed rapidly internationally. It has been vigorously developed and promoted in many countries such as the United States, Japan, Denmark, and the Netherlands; it also has a history of nearly 20 years in China, but due to For various reasons, about half of the more than 40 natural gas distributed energy projects that have been completed are in operation, and half are at a standstill due to problems such as power grid connection, efficiency or technology. my country's natural gas distributed energy is still in its infancy. [0003] At present, there are still many problems in the development of natural gas distributed energy in my country, including obstacles in technology, economy, market and operation management, such ...

AI Technical Summary

Problems solved by technology

[0009] In addition to the above considerable environmental obstacles, the disadvantages of existing distributed energy stations lie in the insufficient use of energy and low utilization efficiency. Traditional distributed energy stations do not consider user loads, and do not adjust the generating power of generator sets according to loads. The excess power generation cannot be stored, resulting in waste of energy
