Integrated redundancy control system of supercharger

Abstract

The invention discloses an integrated redundancy control system of a supercharger. The control system comprises a supercharger body; a compressor body is mounted at the front end of the supercharger body; the front end of the compressor body is communicated with an air suction pipeline through an air filter; a driving motor is mounted at the upper end of the supercharger body; one end of the driving motor is rotationally connected with a driving wheel through a rotating shaft, the surface of the driving wheel is rotationally connected with a driven wheel through a belt, the driven wheel is rotationally connected with a pump wheel through a rotating shaft, the pump wheel drives a turbine to be rotationally connected through a rotor, and an oil cylinder is installed on the supercharger bodyand connected with an oil nozzle filter through an oil return pipeline. Sliding valve adjustment and backflow adjustment are adopted for flow adjustment of the compressor; the adjusting range of a unit sliding valve is 100% to 15%, the adjusting range of a backflow adjusting range is 15% to 0%, flow output under various working conditions is met through sliding valve adjustment, supercharger control and a main engine DCS system are integrated, and remote one-key starting, stopping and comprehensive control over the gas turbine supercharger system can be achieved in a central control room.

Description

technical field [0001] The invention relates to the technical field of supercharger control, in particular to a supercharger integrated redundant control system. Background technique [0002] The two gas turbines currently in production are GE LM6000 aeroderivative gas turbines, which require an inlet pressure of 4.6Mpa±0.05Mpa, while the output of the natural gas pressure regulating system is only 3.0Mpa. Currently, a screw compressor is used to increase the inlet pressure of the unit. KS19SEH / KS0805-Natural gas screw compressor is a rotary displacement compressor. The continuous gas volume is limited to the closed space composed of two rotors and the shell. As the rotor rotates, the closed gas volume decreases and the gas pressure raised. In the early stage of construction, the control system adopts the PLC control system matched with the supercharger manufacturer, and the control program is closed. With the long-term operation of the equipment, technicians cannot optimiz...

Problems solved by technology

In the early stage of construction, the control system adopts the PLC control system provided by the supercharger manufacturer, and the control program is closed. With the long-term operation of the equipment, technicians cannot optimize the automatic control, and access to the host system through communication, and cannot realize full control. Function, insufficient real-time performance of data transmission
