Abstract

The invention discloses an intelligent remote pressure regulating control system, and relates to the technical field of natural gas transmission and distribution control systems. The intelligent remote pressure regulating control system comprises three parts including a PLC control cabinet, a control terminal cabinet and field equipment, the PLC control cabinet outputs a control command to the control terminal cabinet based on intelligent voltage regulation control logics according to parameters collected by the field equipment, and the purpose of automatic pressure regulating is achieved. According to the control terminal cabinet of the intelligent remote pressure regulating control system, a gas storage tank provides gas storage pressure buffering for the pressure regulating system, feeds back gas storage pressure and provides control equipment and parameters such as a gas storage pressure increasing electromagnetic valve, a gas storage pressure reducing electromagnetic valve, a pressure increasing flow control valve and a pressure reducing flow control valve. The intelligent remote pressure regulating control system is stable in operation, the gas storage tank is used for providing air storage pressure buffering, pressure regulating control is facilitated, and the pressure regulating control system is more stable.

Description

technical field [0001] The invention relates to the technical field of natural gas transmission and distribution control systems, in particular to an intelligent remote pressure regulation control system. Background technique [0002] The modern urban natural gas transmission and distribution system is a complex energy comprehensive facility, which consists of transmission and distribution pipeline networks with different pressure levels, various natural gas plants and stations (gate stations, pressure regulating stations, gas filling stations, etc.), information collection, management and maintenance, etc. Software and hardware system composition. [0003] According to its size and functional characteristics, the pressure regulating metering station can be divided into: skid-mounted city gate station, regional pressure regulating cabinet, direct combustion pressure regulating box type, and building pressure regulating box. It has the functions of automatic balance, ultra-h...
