What high speed oscillograph and active power transmitter to be measured were gathered is the stator voltage and stator current of generator
Two sub-values.
Digital electro-hydraulic control system (Digital Electric Hydraulic control system) is referred to as
DEH.The main task of digital electro-hydraulic regulating system for steam turbine is exactly rotating speed, the power for adjusting Turbo-generator Set so as to met
The requirement of electrical network.The control object of steam turbine control system is Turbo-generator Set, and it is by controlling turbine admission valve
Aperture changing into steam flow amount, so as to control the rotating speed and power of Turbo-generator Set.In case of emergency, its security system is fast
Speed closes admission valve, to protect the safety of unit.Due to the unique advantage of hydraulic oil motor, driving force is big, fast response time,
Positioning precision is high, and turbine admission valve is driven using servomotor.Steam turbine control system and its hydraulic regulation security system
It is inseparable.Digital electro-hydraulic control system DEH point is electronic control part and hydraulic regulation security personnel part.Electronics
Control is mainly made up of dcs DCS and the special modules of DEH, and it completes the collection of signal, COMPREHENSIVE CALCULATING, at logic
The task of the aspects such as reason, man-machine interface.Hydraulic regulation security personnel part mainly by electro-control converter, magnetic valve, servomotor, with steam turbine
Structure etc. is constituted, and electrical control signal is converted to hydraulic machinery control signal by it, the aperture of final control turbine admission valve.
Steam Turhine Adjustment device is the core of DEH.It is adjusted by controlling one or more high, middle apertures for pressing pitch
The quantity of steam of whole entrance steam turbine, reaches the purpose of pressure before regulation turbine speed, load or main inlet throttle-stop valve.In addition, adjust
Section device also has the regulatory function for limiting the protection steam turbine such as high pressure blade pressure, high consistency tower, and occurs in mains frequency inclined
From when can increase in time, subtract unit output to adjust mains frequency；Remaining to after load large disturbances even occur removal of load occurs in unit
Band station service maintains the operation of steam turbine constant speed.
Regulating system adopts modularized design, including following components：Speed/spatial load forecasting, main steam pressure control,
Exhaust temperature of HP control, the limiting pressure control of basic pressure, the formation of setting value, control of valve position before HP grade vanes.
The active power transmitter transient characterisitics that wherein present invention is evaluated have important impact to spatial load forecasting in DEH systems.
Active transmitter is important measurement part in DEH, the numerical value conduct measured by the active transmitter of electrical side
Generator actual negative charge values (PEL1, PEL2, PEL3) directly reads in Steam Turhine Adjustment device.In normal operation, from three
Median in load actual value is used as actual load PEL, and exports in following modules and automatic equipment：
(1) operation and monitoring system OM
(2) unit cooperative level BLE
(3) steam turbine open-loop control system DTS
(4) turbine stress evaluation WTG
(5) speed setting value NS
(6) load setting value PS
(7) speed/load adjuster NPR
(8) removal of load identification LAW
Above-mentioned module and automatic equipment can monitor whether three actual negative charge values PEL1, PEL2, PEL3 fail or deviation mistake
Greatly, and by fail message STPEL1/2/3 outputs to OM systems.One actual value failure or deviation are excessive, from remaining two values
In maximum output；Two actual value failures, from the actual value that do not fail；Three actual values fail, from substitution value SV.
Generator actual negative charge values produced by final participate in the control and protection of correlation in will go into corresponding logic.
As the electric energy that generator sends is to be conveyed to user by electrical network.Therefore when unit normally runs, if sent out
The power network switch of motor gate out switch or booster stations is tripped suddenly, or grid power transmission interrupts suddenly, will all cause steam turbine generator
Group removal of load.As the input energy of now steam turbine is much larger than its output energy, the imbalance of both energy will cause vapour
Turbine speed fling lifting.In order to prevent Steam Turbine Over-speed Accident, all of DEH to be designed with the security system of anti-hypervelocity.Room to the west of traditional
Machine is that the DEH systems of representative are generally provided with OPC loops, rises to after 3090r/min causes OPC actions after turbine speed, adjusts
The EH oil pressure ventings of door, pitch quick closedown, so as to reach the purpose for preventing Steam Turbine Over-speed Accident.And Siemens DEH are then adopted
With this diverse mode, it after quick closing valve pitch, unit is cut to from spatial load forecasting and is turned by the identification to load rejection
Speed control, had both prevented Steam Turbine Over-speed Accident, can maintain steam turbine airport logistic park or house load operation again after stabilization of speed.
Removal of load identification function page LAW is divided into two ways removal of load,
First kind of way is that instantaneous load interrupts KU (i.e. short removal of load), and the negative of instantaneous reduction occurs in the power signal of unit
Lotus amount exceedes removal of load and recognizes limiting value GPLSP (moment reduces 40% that performance number is about rated power), you can think unit
Generation instantaneous load interrupts KU.
The second way is long removal of load LAW, while meet following four condition, after triggering short removal of load KU and time delay 2S
The long removal of load LAW signals of triggering 5S fixed width pulses：
A, after Generator Outlet Switchgear and main transformer high side switch closure in time delay 3S
The limit value GP2EB of B, actual load less than twice station-service electric load
C, actual load are higher than inverse probability value GPNEG
D, Payload setting value PSW deduct the limit value GP2EB of the difference more than twice station-service electric load of actual load PEL
It is 150ms fixed width pulses that instantaneous load interrupts KU, and after the signal sends, (KU is not direct for meeting quick closedown pitch
For pitch quick closing valve, pitch quick closing valve is by pitch valve position and the excessive triggering of valve bit instruction deviation), reduce the input energy of steam turbine
Amount, reduces the possible amount of ascending to heaven of turbine speed as far as possible.But interrupting in order to avoid repeatedly there is instantaneous load at short notice, leading
Pitch is caused to frequently switch on, it is 1 that 7S fixed width pulse locking rest-set flip-flops reset terminal is sent out after the triggering of KU signals.Long removal of load LAW triggerings
After can switch the unit method of operation for rotational speed governor load carrying, according to the corresponding relation of load-rotating speed, set by operator
Rotating speed of target is put so as to reach the purpose of control power.
In present embodiment, the model of used equipment is specially：Model PL661 of relay-protection tester is high
Model TK8024 of fast oscillograph, model LCT-CX304 of three-phase phase volt ampere meter, the model of high accuracy number universal meter
For 8846A.
Specific embodiment two：Present embodiment is based on ADPSS emulation system to the one kind described in specific embodiment one
The active power transmitter transient characterisitics index Evaluation Method of system is described further, in present embodiment, short removal of load action
Condition includes：Load disturbance is less than twice more than inverse probability value, actual load more than load saltus step limit value GPLSP, actual load
Station service load limit and spatial load forecasting deviation are more than twice station service load limit.
Spatial load forecasting deviation is the difference of Payload setting value PSW and actual load.
The instantaneous load of the bad initiation of active power transmitter transient characterisitics interrupts KU, and (so-called short removal of load, unit are adjusted
Door quick closing valve), during KU actions, unit pitch is momentarily closed to be decontroled again.Now, if machine is assembled with zero energy protection or related thermal technology
Relay protective scheme, then may trigger zero energy protection or related thermal technology's relay protective scheme action causes unit malfunction off-the-line.
Short removal of load decision condition is as follows：
Emergent load disturbance is more than load saltus step limit value GPLSP (about 70% rated load), and
1. actual load is more than inverse probability value (being typically 3% rated load to the maximum)；
2. actual load is less than twice station service load limit (generally 10% rated load)；
3. spatial load forecasting deviation is more than twice station service load limit (generally 10% rated load)；
4. unit is grid-connected.
If, in the system failure, transient characterisitics are bad for active power transmitter, it is impossible to reflect real changed power, that
Unit DEH will be prevented from fast and accurately adjusting unit output.For example active power transmitter power transient characteristic is not
Good, power distortion causes to meet above-mentioned KU operation conditions, then will result in generator protection logic malfunction, causes unit trip to jump
Machine.Therefore with the operation condition of KU judging the transient characterisitics index of active power transducer.
