Development Of Advanced Application Software For Distribution Master Based On LabVIEW

Now,more and more large-scale professional application software is widely used in the power sector with the continuous development of computer technology.At the same time,human's work has gradually been replaced by the computer.At present the domestic many power supply enterprises in power distribution network automation level is not high,especially in the realization of the function of advanced application of power distribution network which can only realize the single one function and none of the software to be able to put together a variety of functions for management department management and analysis,.Therefore,developing a distribution master station advanced application software has very important significance.In this paper,based on virtual instrument platform distribution master station related functions of advanced application software development and complete the following work :(1)Studied the connections between each system of distribution master station;Further study the distribution center the main function of each system and analyze the way of data connection between them and distribution master station;Analyzing the principle and algorithm of power flow calculation,short circuit current calculation,load forecasting and network loss analysis of distribution master station advanced application functions in detail.(2)Careful study of the LabVIEW software programming method;Designing software that based on the communication module,data processing module as well as the related calculation module of The LabVIEW platform,and making the software can well realize the power flow calculation,short circuit current calculation,load forecast and the analysis of the network loss function based on the state estimation.(3)Through examples demonstrate the network loss analysis capabilities in distribution master station advanced application software;In the example demonstration of power distribution network line loss,the system will alarm when the difference between the actual line loss and the theoretical line loss more than fixed value,which can fully demonstrated the practical performance of this software...
