Research On The Optimization Load Of Natural Gas Pipe Network System In Labview Environment

With the development of the national economy, the demand of the energy is creasing. At the same time, because people pay more attention to the environment ,the requirement about quality of the energy enhance . In all the energy, natural gas undoubtedly is the most clean energy. The project of"natural gas in west area transporting to east area"indicated that our country's natural gas industry will develop rapidly. The optimization of natural gas pipe network system design is very important to the development and usage of natural gas.In order to ensure the natural gas pipe network system operate safely, enhance the efficiency of the natural gas pipe network system , the level of management and quality of feeding, enlarge the number and sort of the users. We design a virtual instrument monitoring and optimization system in the virtual monitoring and control platform of National Instruments Corporation ,namely LabVIEW ( Laboratory Virtual Instrument Engineering Workbench ) .In this system, a series of parameters such as temperature ,pressure, flow rate can be collected and a database has been built .We can regulate and control the upper and lower limit of the temperature, pressure, flow rate. Through it we can know about the character of all kinds of users and the whole networks . Management and optimized load are realized by using this system and the mathematical model of forecast and the optimization of load .All this allows the natural gas pipe network system to be operated in a higher-efficient and more energy-saving situation.All this research is very important for resolving the problem of how the load variety with time affect the natural gas pipe network system.a virtual instrument monitoring and optimization system is design by LabVIEW and data base, In WINDOWS environment.
