Embodiment Construction

[0012] The compressed pressure of the screw machine of the present invention is 0.8 MPaG. After the compression, the gas first enters the storage tank, and then enters the gas generating set for use through the pressure regulation of the pressure regulating valve.

[0013] When unit A stops abnormally, unit B automatically detects the running state of the main motor, and when the main engine of A does not work, it will start unit B immediately, and it will reach full load and normal operation within 5 minutes, which can prevent the gas at the rear end of the screw machine The generator set shuts down, effectively ensuring the stability and reliability of production.

[0014] To sum up, the present invention makes full use of the compressibility of gas, uses storage tanks to store gas, and enables the rear-end generator set to switch compressor units without stopping, which can greatly improve the stability and reliability of the gas generator set, and make Uninterrupted normal...

Abstract

The invention belongs to the field of screw machine compressor composition sledges used in the natural gas industry and particularly relates to a unit seamless switching manner used in the gas power generation industry. The unit seamless switching manner is characterized in that a large-volume storage tank is additionally arranged on a screw unit, the exhaust pressure of the screw unit is increased, the pressure in the storage tank is increased so that gas in the storage tank can continuously supply gas to a gas power generator within unit switching unit, and the purpose of conducting unit switching without halts is achieved. By means of the unit seamless switching manner, compressibility of gas is sufficiently utilized, the storage tank is used for storing gas, a compressor set is switched by a power generator set at the rear end in the condition without halts, stability and reliability of the gas power generator set can be greatly improved, and therefore the power generator set can normally generate power and supply power continuously.

Description

technical field [0001] The invention belongs to the field of screw machine compressor composition skids used in the natural gas industry, in particular to a method for seamless switching of units used in the gas power generation industry. Background technique [0002] The traditional gas station has a backup machine on site. When the normal operating unit suddenly shuts down, it takes a certain amount of time to activate the backup unit. During this period of time when the backup unit is turned on, the back end will have a gas outage, which will affect the well site. Production has a certain impact. Contents of the invention [0003] In order to solve the above technical problems, the present invention invents a safe and reliable unit seamless switching mode. [0004] In order to achieve the above effects, the invention adopts the following technical solutions: [0005] A method for seamless switching of units, which is characterized in that a large-volume storage tank i...
