The analog signals and the analysis result thereof that gather synchronize in clock module, it is achieved on-the-spot examination
Test the contrast output function of result and regulation goal instruction.
Fig. 2 is for implementing technical scheme figure, and Fig. 3 is embodiment working-flow figure, scheduling
Sending regulating command to the EMS of wind energy turbine set, EMS receives instruction and passes through
Calculate, be sent to each management system by regulation strategy, be finally handed down to blower fan by management system
Group, SVG/SVC(reactive power compensator) perform.Intelligent tester is directly read by message
Taking dispatching down distributing instruction curve, test wind energy turbine set is meritorious effectively, intuitively, idle control ability
And response time.
Before formal test, consult PORT COM IP, logical with wind energy turbine set EMS producer
News port and communication protocol, the conversion coefficient of setting value.Monitoring management machine in position is soft on a tester
Corresponding " distant place soft start IP " is arranged to consistent with this parameter by part with " port ".
After program starts, automatically according to the IP set and port and wind energy turbine set energy management system
Communication link is found in construction in a systematic way, an independent intercepting thread monitor the message on this link.
Set analog acquisition passage according to field connection situation and calculate passage, remote regulating signal
The parameters such as protocol type, data type, informosome address, and according to wind energy turbine set energy management
The negotiation result of system manufacturers sets taking advantage of the factor and adding the factor (by taking advantage of the factor and Jia Yin of signal
Son converts the data into the setting value of correspondence).
Starting record ripple after being provided with, now the AD collecting thread of tester is started working, record
Start the voltage of real-time rendering wind field, electric current, changed power curve on ripple interface, and enter pre-
Record pattern, meanwhile, instructs according to remote regulating, parses target set point, also served as one
Curve (sample rate gathers consistent with AD) is plotted on same picture, when intercepting thread receives
To when being set as the remote regulating instruction triggering signal, automatic triggering following records ripple.Owing to AD gathers
Thread is synchronous operation the most side by side with remote regulating instruction intercepting thread, so can be described as on the time
Complete Synchronization.After record ripple terminates, by adjusting the most meritorious, the idle electricity of contrast wind energy turbine set
The curves such as pressure and regulation goal setting value curve, can conveniently, accurately, timely, intuitively see
Each remote regulating amount contrasts with measured value trend, provides foundation for relating to net test.
Fig. 4 is certain wind energy turbine set electric hookup that scheme implements test.
Fig. 5 is the oscillogram issuing the electric current of desired value, active power manually, yellow in figure,
Three waveforms green, red represent A, B, C three-phase electricity flow valuve respectively, and blue-colored waveform represents meritorious
Performance number, black wave represents the active power desired value that scheduling manually issues.Save regulating mechanism people
Operation blower fan under #2 main transformer was manually assigned desired value of once gaining merit every 4 minutes by work, logical
Cross Fig. 5 it is found that because Artificial Control assigns instruction, so meeting between the instruction every time assigned
There is artificial time error, but blower fan system perform the most accurately saving the regulating command adjusted,
The change curve of measured current and active power all can reflect active power by 80% specified
Value is down to 20% rated value, then is risen to the rated value of 80% by 20% rated value.
Fig. 6 is that wind field reactive voltage raises curve chart, and wind field voltage is adjusted up process description:
1) A point receives the instruction of scheduling rising 2kV；2) through calculating and the instruction transmission of 6.7s
Rear TCR starts to regulate (B point), until SVC is idle is output as 0Mvar(C point)；3)
When SVC is idle be output as 0Mvar time, start to regulate the idle output of blower fan group, quickly
0Mvar(D point is down in the idle output of perception of blower fan group)；4) blower fan group perception is idle defeated
Going out after being down to 0Mvar, SVC continues regulation, exports capacitive reactive power, enters the calculating of too much wheel
E point is arrived with regulation.Voltage reaches to regulate desired value, and regulation completes；5) E point is received again
The instruction of 1.8kV is risen to scheduling；6) through a regulation taking turns SVC, open after arriving F point
Begin regulation blower fan group, and blower fan group starts to export capacitive reactive power；7) blower fan output capacitive reactive power reaches
After the upper limit, SVC starts again at regulation (G point)；8) SVC is after regulation several times,
Although grid-connected point voltage does not arrive desired value, but SVC capacitive reactive power the most also reaches in output
Limit, therefore stops regulation.
Present invention firstly provides the method utilizing communication packet to trigger test wind energy turbine set response time,
