Research On Operation Performance Evaluation Of Nuclear Power Plant

Using evaluation theory to construct an index hierarchy system to study nuclear power plants,data can reflect the status of nuclear power plant operating performance,and then analyze the state of various system parameters in the system,so as to realize nuclear power plant state analysis and risk estimation.The operation and operation of technical personnel provide theoretical support and technical guidance.This paper first introduces the background of nuclear power plant operating performance evaluation research and the current research status at home and abroad,and proposes an overall framework for nuclear power plant operating performance evaluation,and then conducts related research on nuclear power plant operating performance evaluation criteria,and obtains the evaluation parameters Based on the group criteria,an index system for evaluating the operational performance of nuclear power plants has been established;and index standardization criteria have been obtained through research,and the parameters of different types and trends in the index system have been standardized.At the same time,according to the characteristics of different indexes’ influence on the overall operating performance,the weight assignment of indexes is studied.Based on the introduction of conventional weighting methods,this article discusses weight correction methods and characteristics,such as comprehensive weighting methods that integrate subjective and objective factors,expert experience correction weighting methods that consider expert experience,and health change weighting for indicators that deviate from the normal state.method.And these methods are described in detail and the calculation steps are demonstrated.After obtaining the standardized values and weight values of the indicators,the algorithm research of the nuclear power plant operating performance evaluation model was carried out,considering the hierarchy and deviation degree of the evaluation indicator system,and based on the conventional evaluation methods,focusing on the operating performance characteristics of the nuclear power plant and the conventional evaluation The defect of the method,a comprehensive evaluation model algorithm based on the theory of deterioration degree health value is proposed to solve the problems of index ambiguity factor,accurate evaluation value demand,and index deviation degree weight change.Finally,the characteristics and applicability of each method are summarized and analyzed.This research carried out the engineering realization of the evaluation theory,used the C#language to develop the Win Form interface on the Visual Studio 2010 platform,and used the SQL Server 2008R2 database to realize the data storage and call,and obtained the modular design,parametric design,visual design,and rapid evaluation The operating performance evaluation system software of nuclear power plant of the process.Finally,an evaluation example was carried out using the operating data of the Qinshan Nuclear Power Plant,showing the operating process of the nuclear power plant operating performance system software evaluation.Through the establishment of the index system,index standardization,index weight assignment and evaluation model algorithm modules,the final nuclear power plant operation was obtained.The performance evaluation results achieved the goal of evaluating the operating performance of nuclear power plants,and verified the applicability of the overall evaluation theory and the feasibility of the software..
