摘要
如果检测实验室出现电能质量问题,就将直接影响实验室的安全,因此提出检测实验室电能质量风险预测和控制技术。通过获取并预处理电压、电流、有功功率、无功功率等检测实验室的历史电力数据,构建一个灰色模型来预测未来电能质量风险等级,并引入风险管理机制进行检测实验室电能质量风险控制。实验结果表明,设计技术预测的检测实验室电能质量风险的正确率高达97.3%,实际应用性能良好。
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 historical 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.
