基于友好界面的短路电流计算程序实现摘要在电力工程设计的过程中,短路电流的计算是非常重要的设计内容。短路电流的计算结果与电力系统的安全、可靠性有非常紧密的联系。随着我国社会经济的发展,电力系统的功能不断完善。就发电厂而言,发电厂的容量随着市场的需求而不断增加,因此对短路电流也提出了更高的要求。文章在计算短路电流的过程中,选择了基于导纳矩阵的计算方式,并且通过软件编程开发了界面友好的应用程序。文章在使用导纳矩阵计算短路电流时,主要是以电网节点的导纳矩阵作为数据模型参考。文章在计算的过程中,充分考虑了电抗和电阻。因此有效的提高了计算结果的精确度。文章在设计短路电流计算程序过程中,首先确定了计算的方法,在软件开发的过程中依据模块化的编程思路,绘制了每个模块的流程图从而确保软件代码的移植性和可维护性。文章选择c#语言作为开发语言,并且通过计算机算例验证应用程序的准确性。文章利用计算机算例测试的结果表示,在程序中输入参数,可以有效的计算出元件的阻抗,且推算出节点导纳矩阵,从而通过分解可以计算出短路阻抗。此外,该应用程序在计算短路电流的同时,还计算了非故障点。该用程序输出计算结果时还会为用户展示原始的参数、导纳矩阵等相关数据,有利于用户对整个计算过程的检查,便于用户及时发现问题,并及时的纠正。关键词:短路电流计算;节点导纳;可视化界面;计算机算法;C#ABSTRACTIntheprocessofpowerengineeringdesign,thecalculationofshort-circuitcurrentisaveryimportantdesigncontent.Theshort-circuitcurrentcalculationresultsarecloselyrelatedtothesafetyandreliabilityofthepowersystem.Withthedevelopmentofsocialeconomyinourcountry,thefunctionofthepowersystemhasbeencontinuouslyimproved.Inthecaseofpowerplants,thecapacityofpowerplantscontinuestoincreasewiththeneedsofthemarket,andthereforehigherdemandsareplacedonshort-circuitcurrents.Intheprocessofcalculatingtheshort-circuitcurrent,thearticlechosethecalculationmethodbasedontheadmittancematrix,anddevelopedanapplicationwithfriendlyinterfacethroughsoftwareprogramming.Whentheadmittancematrixisusedtocalculatetheshort-circuitcurrent,thearticlemainlyusestheadmittancematrixofthegridnodeasareferenceforthedatamodel.Inthecalculationprocess,thearticlefullyconsideredthereactanceandresistance.Therefore,theaccuracyofthecalculationresultiseffectivelyimproved.Intheprocessofdesigningtheshort-circuitcurrentcalculationprogram,thearticlefirstdeterminedthemethodofcalculation.Intheprocessofsoftwaredevelopment,accordingtothemodularprogrammingideas,theflowchartofeachmodulewasdrawntoensuretheportabilityandmaintainabilityofthesoftwarecode..Thearticleselectsc#languageasthedevelopmentlanguageandverifiestheaccuracyoftheapplicationprogramthroughcomputercalculations.Thearticleusestheresultsofcomputertestcasestoshowthatinputtingparametersintheprogramcaneffectivelycalculatetheimpedanceofthecomponentandcalculatethenodeadmittancematrix,sothattheshortcircuitimpedancecanbecalculatedthroughdecomposition.Inaddition,theapplicationcalculatestheshort-circuitcurrentandalsocalculatesthenon-faultpoint.Whentheprogramoutputsthecalculationresults,itwillalsodisplaytheoriginalparameters,admittancematrix,andotherrelevantdatafortheuser,whichisbeneficialtotheuser'sinspectionoftheentirecalculationprocess,andfacilitatestheuser'stimelydetectionofproblemsandtimelycorrection.Keywords:shortcircuitcurrentcalculation;nodeadmittance;visualinterface;computeralgorithm;c#目录摘要.......................................................................................................IABSTRACT...............................................
