Automatic power generation control-based water pumping and energy storage unit automatic startup-shutdown control method

The invention discloses an automatic power generation control-based water pumping and energy storage unit automatic startup-shutdown control method. The control method comprises the following steps of(1) performing expansion of automatic power generation control system models, and adding a water pumping and energy storage unit basic control model; (2) setting the water pumping and energy storageunit basic control model; (3) calculating an automatic startup-shutdown control instruction, wherein the control instruction is a startup capacity value; and (4) performing safety verification on thestartup capacity value, and issuing the startup capacity value after verification is passed. By issuing remote signaling on the main station side, working condition conversion, comprising startup andshutdown, of the water pumping and energy storage unit can be realized, troublesome phone communication by a dispatcher can be avoided, and work pressure can be relieved; in addition, the backup and frequency control levels of the power grid and the day-ahead power generation plan arrangement and dispatcher human decision making can be taken into comprehensive consideration according to the operation condition of the power grid; and therefore, the number of startup and pump starting times and opportunity of a water pumping and energy storage power plant can be changed automatically, and the peak shaving and frequency modulating characteristics of the water pumping and energy storage power plant can be given into full play, thereby ensuring frequency operation safety of the power grid.

SVM-RF-based decision rule extraction and reduction method

InactiveCN109978050AReduction to the maximum extentNumber of reduction rulesCharacter and pattern recognitionNODALData set
The invention discloses an SVM-RF-based decision rule extraction and reduction method, and belongs to the technical field of computer and information science. The method comprises the following stepsof training an SVM by using data to obtain a classifier and a support vector; generating new data characteristics by adopting a regeneration tree method, obtaining a new data label by using an SVM (support vector machine), and integrating the new data to obtain a most information amount of data set; training a random forest model by using the data set with the maximum information amount to obtaina plurality of decision-making trees; fusing the terminal node similarity and the decision tree performance similarity of the decision tree into new similarity by introducing a trade-off factor, and reducing the redundant decision tree based on the similarity; and finally obtaining a rule set by using a decision tree traversal method. The decision rule extraction and reduction method provided by the invention not only gives consideration to higher accuracy of the SVM-RF model, but also can avoid that the extracted decisions are too many and are not easy to understand by people, thereby helpingthe SVM-RF model to popularize in practical application and playing a role in assisting human decision making.

Oil wellmaximum yield mode control method based on stroke ratio and dynamic control diagram

InactiveCN109870902ARealize the purpose of reducing production costs and increasing efficiencyReduce oil recovery energy consumptionAdaptive controlMode controlEngineering
The invention relates to an oil well maximum yield mode control method based on the stroke ratio and a dynamic control diagram. A ground indicator diagram of an oil well is analyzed, the effective stroke of the oil well is calculated, the change condition of the stroke ratio is analyzed, under the premise that the pump efficiency is as high as possible, a pumping unit is maintained to run at the low frequency, that is, based on the principles of the high pump efficiency and low energy consumption, an intelligent optimization frequency conversion scheme of the oil well is designed, and a frequency conversion control strategy is corrected combined with evaluation results of the dynamic control diagram of the oil well, so that the oil well maintains a reasonable maximum yield model to produce. Under traditional frequency conversion control modes, frequency conversion control of a rod pumping well is still dominated by human decision-making, real-time adjustment of a pumping well is difficult to realize, according to a rod pumping well intelligent frequency conversion control method based on the indicator diagram stroke ratio and the oil well dynamic control diagram, the oil well is optimized and controlled in real time, the oil well is subjected to frequency conversion optimization control while the reservoir potentiality is exerted to the maximum limit, oil extraction energy consumption is lowered, the system efficiency is improved, and the purposes of cost lowering and efficiency improving of production of an oil field are achieved.
