Technology of Risk Prediction and Control for Power Quality in Testing Laboratory
The occurrence of power quality problems will directly affect safety of testing laboratory.The risk prediction and control technology of power quality in testing laboratory is proposed.The method obtains and pre-processes the histor-ical power data of the testing laboratory such as voltage,current,active power and reactive power,builds a gray model to predict the future power quality risk level,and introduces a risk management mechanism to control power quality risk of the testing laboratory.Test results show that the accuracy rate of the designed technology in predicting power quality risk in the laboratory is as high as 97.3%,and the practical application performance is satisfactory.
