摘　　要：为实现电能计量器具自动化检定系统期间核查高质量、高效率及低成本的多目标要求,建立了以最小化综合核查成本、最大化检定效率为目标的数学模型。针对该模型的求解,提出一种改进快速非支配多目标优化算法(INSGA-Ⅱ),通过设计多点交叉变异策略提高种群的搜索能力,并采用扰动种群提高种群的多样性,防止种群陷入局部最优。通过算例仿真以及算法对比,验证了该模型和算法的有效性和可行性。结果表明,所提INSGA-Ⅱ算法可有效求得问题的非支配解,对提高核查质量、核查效率和降低核查成本具有指导意义。最后,将模型最优解应用于国网湖北省电力计量中心低压电流互感器自动化检定系统期间核查,绘制控制图监测检定系统运行状态,确保测量过程可控。In order to achieve the multi-objective requirements of high quality,high efficiency and low cost of the automatic verification system of electric energy metering instruments intermediate checks,a mathematical model was established to minimize the comprehensive verification cost and maximize verification efficiency.To solve the model,an improved fast non-dominated multi-objective optimization algorithm(INSGA-Ⅱ)was proposed,which improved the searching ability of the population by designing a multi-point crossover mutation strategy,and using perturbation population to improve the diversity of the population and prevent the population from falling into local optimum.The effectiveness and feasibility of the model and algorithm were verified by example simulation and algorithm comparison.The results showed that INSGA-Ⅱalgorithm can effectively obtain the non-dominated solution of the problem,which is of guiding significance to improve the verification quality,verification efficiency and reduce the verification cost.Finally,the optimal solution of the model was applied to the intermediate checks of the automatic verification system of low-voltage current transformer in Hubei Electric Power Metering Center of State Grid,and the control chart was drawn to monitor the operation status of the verification system online,which ensured that the measurement process was always in the state of statistical control.
