Description
Technical field
The present invention relates to automatic control technology fields, and in particular to a kind of gas turbine lubrication EFM Electronic Fuel Management.
Background technology
Gas turbine engine lubricant system is in the startup of unit, normal operation and stopping process, to combustion engine and generator
Bearing, gear-box offer quantity is sufficient, temperature and pressure are appropriate, clean lubricating oil, to prevent burn-out of bearing, axle journal overheat
It is bent and causes unit vibration；In addition, a part of lubricating oil separation is out supplied to hydraulic oil to system after filtering, as
The control oil of gas fuel system and compressor inlet guide vane system.Some removes tripping oil, jacking oil system.Combustion gas
Turbine lubricating oil system would generally be equipped with two oil pumps, and a master one is standby, active and standby each other, is supplied for gas turbine engine lubricant system
Oil, so the fuel feeding of two oil pump normal tables of control is vital.
Current gas turbine lubricates EFM Electronic Fuel Management, and hardware aspect becomes an entirety with gas turbine domination set, main
To use distributed, more redundancies, non-linear, multi-functional Digital electronic control system, three big heavy duty gas turbine manufacturer GE public
SPEEDTRONIC MARK series control system, the TELEPERM XP series control systems of Siemens Company and the Mitsubishi of department
The DIASYS Netmation complete control systems of company.
The control program of the double AC Lub oil pumps of gas turbine is as follows at present：
As main oil pump entry condition：Grease pump, which starts, to be enabled, and has selected the oil pump as main oil pump, and overload is cut
It is changed to vacation.
As auxiliary oil pump entry condition：Main oil pump overload or charge oil pressure low (control enables time delayed signal) or main oil pump
Not running (control enables time delayed signal).
Condition of self-locking：It is false (button) that another oil pump, which is selected, as the signal of main oil pump.
Overload handover module：Select the oil pump as main oil pump and oil pump overload, condition of self-locking：Active and standby oil pump selection letter
Number it is false (button).
Current gas turbine control system, Properties Control have no longer been unique competitive advantage, high reliability, online dimension
Repair, the information technologies such as at low cost and friendly man-machine interface start to become contemporary heavy combustion engine control system market competition it is excellent
Gesture is directed to the present situation of state's field of internal combustion engine, and many users are limited by the high maintenance cost of turbine control system, if one
The control system of combustion engine is covered while meeting basic user demand, and there is good reliability and reasonable prices, that
There to be very much the market competitiveness.
Presently, there are double AC Lub oil pumps control algolithm in, the entry condition slitting of auxiliary oil pump is arranged side by side, and
Main oil pump startup program is programmed in one big module, and the switching condition after oil pump breaks down only has Oil pump electrical machinery thermal overload
One condition, underaction；
Auxiliary oil pump entry condition：Charge oil pressure is low, main oil pump not running, a time delay condition individually arranged side by side, this
Condition is not comprehensive enough, not accurate enough.
Condition of self-locking has used the button signal of selection main oil pump, and button signal is pulse signal.Meanwhile different control systems
The operational capability of system processor is different, different to the scan period of program, the sequencing that each logic module of control program executes
Also different (adjustment difficulty for the sequencing that these logic modules execute is very high) are likely to result in the manual switching of active and standby oil pump
Failure, the more serious failure for possibly even leading to equipment are damaged.
