Description
Technical field：
The utility model belongs to gas-turbine plant technical field, and in particular to a kind of gas turbine inlet guide vanes control system
System.
Background technology：
Gas turbine inlet guide vanes main function has:1. in combustion engine operational process, prevent compressor from surge occurs;2. work as
Gas turbine application, by the angle of regulating gas turbine air inlet guide vane, makes gas turbine when combined-cycle power generation plant project
Exhaust gas temperature be maintained at higher level, so as to improve the overall efficiency of circulating power station.
There are mainly two types of modes for gas turbine inlet air wicket gate control control system at present：1. using pneumatic linear actuator as executing agency
Control system；2. using hydraulic cylinder as the control system of executing agency.Using pneumatic linear actuator as the control system of executing agency, mostly with pressure
Gas moves for air source pusher cylinder and then controls gas turbine inlet guide vanes angle between mechanism of qi grade.There are air inlets for this kind of control system
Guide vane angle control accuracy is low, the easy bite of pneumatic cylinder, the problems such as combustion turbine exhaustion temperature is non-adjustable.Using hydraulic cylinder as execution
The control system of mechanism continuously controls the angle of combustion engine turbine entry guide vane according to combustion engine operating status.This kind of control system
It is independent a set of oil system and control system mostly, there are weight is big, volume is big, high failure rate, of high cost, control system is multiple
The problems such as miscellaneous.
Utility model content：
The purpose of this utility model be in order to solve low gas turbine inlet guide vanes control accuracy, high failure rate, volume it is big,
The problem of weight is big has designed and developed a set of gas turbine inlet guide vanes control system using electric cylinder as executing agency.With electricity
Dynamic cylinder is executing agency, and accurate, rapid, continuous control is realized to gas turbine inlet guide vanes angle.Purpose is to ensure
Compressor surge, the whole efficiency for improving gas turbine, the production cost for reducing gas turbine are prevented during gas turbine operation.
The technical solution adopted in the utility model is：A kind of gas turbine inlet guide vanes control system, the system include using
Pass through cable and combustion gas wheel in the electric cylinder and entry guide vane driver, entry guide vane driver for automatically controlling entry guide vane rotation
Machine controller connects.
Further, the electric cylinder carries out power transmission by mechanical transmission mechanism.
Further, the entry guide vane driver receives the angle signal of gas turbine controller by communication modes.
The gas turbine controller calculates the optimal angle of entry guide vane according to combustion engine operating status；Gas turbine control
Optimal angle signal is passed to entry guide vane driver by device processed by hardwire or communication modes；Entry guide vane driver is accurate
Control inlet guide vane angle.
The beneficial effects of the utility model：The gas turbine inlet air wicket gate control system is using electric cylinder as executing agency, root
According to the angle of the continuous high-precision control air inlet guide vane of the operating status of gas turbine, the maximized effect for improving gas turbine
Rate and safety.Its with it is small, light-weight, control accuracy is high, at low cost, easy to maintenance, to be easy to rebuilding old equipment etc. excellent
Point.Its advantage is mainly：
（1）, easily to gas turbine, old control of inlet guide vanes system carries out upgrading；
（2）, floor space it is small, arrangement is convenient；
（3）, be accurately controlled gas turbine inlet guide vanes angle, improve the efficiency of gas turbine；
（4）, reduce gas turbine overall manufacturing cost；
（5）, improve gas turbine varying duty ability.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model.
Specific embodiment：
With reference to Fig. 1, a kind of gas turbine inlet guide vanes control system, which includes automatically controlling entry guide vane rotation
The electric cylinder and entry guide vane driver, entry guide vane driver turned is connect by cable with gas turbine controller；The electricity
Dynamic cylinder carries out power transmission by mechanical transmission mechanism；The entry guide vane driver receives gas turbine control by communication modes
The angle signal of device processed.
Gas turbine controller drives according to the optimal angle of the state computation exit port guide vane of gas turbine, entry guide vane
Device driving electric cylinder action ensures that the angle of entry guide vane is identical with optimal angle.Gas turbine controller acquires the state of combustion engine
Parameter calculates the optimal angle of entry guide vane such as rotating speed, pressure, temperature, power.Entry guide vane driver is counted in real time
The deviation of inlet guide vane angle and optimal angle is calculated, the distance of electric cylinder movement is calculated according to angular deviation and drives electric cylinder
Action ensures angular deviation within the range of permission.
