Description of drawings
Fig. 1 is primary frequency modulation " frequency "-" original meritorious "-" filtering is meritorious "-" filtering AGC influence is meritorious " response curve.
Embodiment
Primary frequency modulation on-line evaluation method based on WAMS filtering AGC influence provided by the invention, the WAMS data are adopted in this method computational analysis, monitoring the whole network system frequency, when frequency generation disturbance and when satisfying the primary frequency modulation design conditions, judge whether to exist the AGC instruction, automatically the whole network generator is carried out the primary frequency modulation performance analysis, the result contains difference coefficient, regulate electric weight, primary frequency modulation performance parameter such as correct operation whether, the frequency modulation dead band, response time, primary frequency modulation parameter examination amounts such as stabilization time, and result of calculation is saved in database " primary frequency modulation performance table ".Concrete implementation step is as follows:
Step 1: the monitoring machine class frequency, judge whether the occurrence frequency disturbance, according to disturbance characteristic difference, be divided into big disturbance and microvariations; The occurrence frequency disturbance means that the unit primary frequency modulation should move, and makes frequency retrieval to 50Hz by increasing or reduce to gain merit;
Step 2: the machine class frequency after the monitoring disturbance, judge whether primary frequency modulation finishes; Concluding time be in stabilization time frequency retrieval to the primary frequency modulation dead band with interior time point, the primary frequency modulation dead band generally is made as 0.033Hz, does not return in the dead band as frequency in stabilization time, then when arriving stabilization time, is judged to primary frequency modulation and finishes;
Step 3: the monitoring power of the assembling unit, judge whether power responds; Monitor variable power the zero hour from primary frequency modulation,, be judged to power response as surpassing the variable power threshold value;
Step 4: the record primary frequency modulation meritorious data zero hour before, whether judge meritorious rate of curve greater than definite value, if any, then be judged to and exist this moment AGC to instruct, when the subsequent calculations primary frequency modulation performance, want the influence of filtering AGC.
Step 5: calculate the primary frequency modulation performance parameter, as difference coefficient, contribution electric weight and correct operation etc. whether; And check the primary frequency modulation parameter, as frequency modulation dead band, response time, stabilization time; Deposit the result in oracle database at last.
Difference coefficient computing formula :-(fm-f0) the * fn of * Pn*100%/(Pm-P0).
The contribution electric weight: active power is from the primary frequency modulation integration amount of the zero hour to the finish time.
Correct operation whether: if frequency descends, the contribution electric weight increases, and is judged to correct operation; Otherwise mistake;
If frequency rises, the contribution electric weight reduces, and is judged to correct operation; Otherwise mistake.
Be a preferred embodiment of the present invention below, the technical scheme that the present invention realizes be described further below in conjunction with this accompanying drawing.
Embodiment
As shown in Figure 1: the grey curve is original meritorious curve, and green curve is the meritorious curve through Filtering Processing, and red curve is the meritorious curve after the filtering AGC influence, and blue curve is a frequency curve.
At red vertical curve frequency jitter has taken place constantly, frequency reduces, the primary frequency modulation action, and meritorious should increasing exerted oneself.The green curve of filtering AGC instruction never sees that meritorious not increasing exerted oneself, reduced on the contrary and exerted oneself, and from surface phenomena, the primary frequency modulation stroke defect, corresponding punishment will be accepted in this generating plant.
From the meritorious curve of primary frequency modulation before the zero hour, green curve has become downtrending, and meritorious curve should be approximated to straight line under the normal condition, and by corresponding calculated, judging has the AGC instruction issuing this moment.The reverse meritorious matched curve to the AGC commanded response of stack can obtain the curve that red filtering AGC influences on original meritorious curve.Can obviously find out from red curve, meritorious present the normally steadily powertrace of primary frequency modulation before the zero hour, after primary frequency modulation began, meritorious curve presented ascendant trend, reflect the action command that this unit has correctly responded primary frequency modulation, also will become award the punishment of this generating plant.
The present invention adopts the WAMS system data, and it has gathers density height, data precision height, data and have advantages such as high precision markers.The Refresh Data time can reach 10ms, situation of change that can the monitored amount of accurate response.
The present invention proposes the algorithm of filtering AGC influence.Meritorious variation under the normal condition is little, and meritorious curve can be approximated to straight line.Behind the AGC instruction issuing, meritorious increase or minimizing meeting mean allocation respond to per minute, and therefore, meritorious AGC response curve can fit to the fixing oblique line of a slope.
The moment meritorious data recording for the previous period takes place with primary frequency modulation in the present invention, analyzes the meritorious data that it belongs to normal meritorious data or response AGC instruction.Have a fixing slope if find this segment data, and greater than setting value, then judging there is the AGC instruction issuing this moment, and calculates the AGC slope of a curve according to this segment data, simulates the meritorious response curve of AGC.
Analyze primary frequency modulation having under the situation of AGC instruction, the meritorious curve of the gathering meritorious response that superposeed in real time to primary frequency modulation and two kinds of instructions of AGC, this can not the actual response primary frequency modulation performance, even also might draw opposite conclusion.The meritorious response curve of the AGC of this method filtering match on the meritorious curve basis of gathering in real time can only be responded the meritorious curve of primary frequency modulation.Empirical tests, this method can be reacted the meritorious response condition to primary frequency modulation of unit more accurately.
Because WAMS data acquisition density is higher, refresh time can reach 10ms, satisfies the requirement of real time execution, has realized the assessment of primary frequency modulation checking system real time on-line monitoring.
The invention provides a kind of primary frequency modulation on-line evaluation method based on WAMS filtering AGC influence.Progressively implementation along with factory's net separation and assistant service, grid company is more and more urgent to the examination of generating plant primary frequency modulation, particularly when big disturbance takes place, primary frequency modulation is as the first line of defence of keeping frequency stabilization, show the status of particular importance, grid company often wishes to check immediately the action situation of generating plant primary frequency modulation.The present invention has realized the assessment of primary frequency modulation on-line monitoring, can provide primary frequency modulation monitoring and evaluation result in real time, this method adopts advanced WAMS system data to calculate, and the method for filtering AGC influence proposed, the result accurately and reliably, can react generating plant primary frequency modulation situation more really, obtain effect preferably in actual applications.
Should be noted that at last: only illustrate that in conjunction with the foregoing description technical scheme of the present invention is not intended to limit.Those of ordinary skill in the field are to be understood that: those skilled in the art can make amendment or are equal to replacement the specific embodiment of the present invention, but these modifications or change are all among the claim protection domain that application is awaited the reply.
