Analysis And Design Of The Energy Consumption Of The Substation On Line Monitoring In Radio And Television Building

In recent years,with the rapid development of our national economy,great changes have taken place in the power distribution system in our country,many substations,substation automation technology with the development of electric power,electric power monitoring and management of new technology,smart grid technology began to rise;and energy consumption monitoring services for electric power systems,with the development of intelligent the rapid development of grid technology.10kV substation broadcasting system,as with many old substation power system,no automation system of substation inspection personnel key electrical parameters and data,mainly through the data acquisition timing manual mode and timing report data,this data can not be timely and effective collection,is not conducive to the statistical analysis of the data.Therefore,the design ideas of this paper are as follows:firstly,we analyze the situation before the transformation of the substation,according to the experience and the deficiency of the long-term operation,and draw a practical demand.According to the new substation unit must have the information monitoring capability requirements,upgrading of online monitoring system of substation,installation and application of a substation in the unit for on-line monitoring and analysis platform of energy consumption.As the state monitoring system of electric equipment and energy consumption analysis of the most important part of the online monitoring platform can provide first-hand data for substation technology and management personnel,to focus on energy consumption of energy equipment such as energy consumption monitoring substation transformer and low voltage power distribution system.From the point of view of economic and convenience of engineering design,the communication system of the lower layer adopts RS-485 communication protocol.On line monitoring system hardware part uses the market mature product equipment,the article elaborated the hardware system construction and the installation process in detail.The software part,according to the actual needs of the unit,as well as to save the cost of software acquisition considerations,decided to use Lab VIEW to develop the PC software,the development process in this paper will be described in detail.The design of the project includes the transformation of the substation system,the overall scheme design of the monitoring system,the installation and construction of the hardware equipment,the content of the software development and design.From the technical,economic,practical,easy to maintain and so on,it is suitable for the radio and television substation design and equipment selection,determine the reasonable design process.Finally,the system realizes the statistics and analysis of the basic electrical parameters,energy consumption and efficiency of the transformer,as well as the statistics of the basic electrical parameters and energy consumption data of the low voltage building load.The application of the system,to achieve the full monitoring of energy consumption through online monitoring,to provide a basis for energy saving effect.To achieve a comprehensive monitoring of the operational status of the transformer and low voltage building energy consumption of accurate statistics,the project can be used in various types of buildings to promote the distribution system,to achieve a wider range of applications.
