Remote Power Consumption Monitoring And Power Supply Performance Evaluation Of High-Power Equipment

Among the total installed capacity of China's power grid,high-power equipment accounts for a large part,which is a large consumer of enterprise energy.However,the company's original monitoring and management is simple and extensive,relying on personnel experience,and the monitoring content is simple,including voltage.Basic energy data such as electricity consumption is difficult to ensure the healthy operation of high-power equipment and comprehensively examine its power supply performance.Therefore,remote monitoring technology has become a research hotspot in recent years.However,most remote monitoring systems still have problems such as difficult information integration and low level of intelligent application,which is difficult to put into use.The remote monitoring technology in some developed countries in Europe and America is relatively mature.There is a set of digital platforms to monitor high-power equipment,and based on this,a scientific power supply performance evaluation is performed for each equipment monitored.Throughout the country,there is widespread monitoring and light analysis,and monitoring lacks experience and research,and the accuracy is not high.Therefore,it is of great significance to design and build a complete set of high-power equipment remote energy consumption monitoring system to help enterprises intelligently manage and optimize equipment,and to evaluate the power supply performance of each high-power equipment through data analysis.In this paper,the whole remote energy consumption monitoring system is divided into two parts,one is the energy data acquisition module,and the other is the high-power equipment remote energy consumption monitoring cloud platform.The two use GPRS networking technology for data transmission.The core MCU of the energy data acquisition module selects KE06 from Freescale,and is equipped with a high-precision three-phase energy metering chip ATT7022 E sampling,thereby expanding the module hardware design.Based on functional requirements,build a software framework and implement specific functions,and design a series of communication mechanisms to ensure communication stability.To monitor the cloud platform,comprehensively analyze the needs of the entire platform,select PHP as the development language and ThinkPHP as the system development framework,and build the entire cloud platform in the integrated environment of the warmpserver,including the data table of the cloud platform database and the specific software function modules.design.Based on the built-in high-power equipment remote energy consumption monitoring system,this paper further studies the power supply performance of high-power equipment,designs the entire power supply performance evaluation program,determines the indicators that can effectively reflect the power supply performance of high-power equipment and gives scientific calculations.In this method,the linear combination weighting method combining entropy method weighting and AHP method weighting is used to scientifically weight each power supply performance index.The final design adopts the gray theory method to do the power supply performance of high power equipment.A comprehensive assessment.In order to verify the feasibility of the whole monitoring system and power supply performance evaluation program,this paper first built the whole test platform in the laboratory,and tested the vibration resistance of the energy data acquisition module and the basic acquisition and communication functions of the system.After that,the whole system was put into use by the enterprise,and a certain period of monitoring was carried out.The detailed electrical performance parameter chart of the equipment was obtained,and the power supply performance of the monitoring high-power equipment was comprehensively evaluated,thus verifying the feasibility of the whole monitoring system and the power supply performance evaluation program..
