Abstract

OpenDSS refers to the open source implementation of the Distribution System Simulation (DSS). It is a general-purpose frequency-domain simulation engine having special features for creating models of electric power distribution system and performing many types of analyses related to distribution planning and power quality. It can perform electromechanical transients and dynamic analysis. In this work, two test systems representing radial and ring networks are setup in OpanDSS and suitable lines and proper rating of transformer are selected . Along with this, the capacitor control and reactor control needed within the distribution system are implemented. Different fault conditions are applied to the distribution system and analysed. The Dispersed Storage and Generation (DSG) devices ability to handle a distribution system during islanding condition is also analysed. The main objective of the work is to check the available features of OpenDSS for analysing the Distribution networks. The OpenDSS will get data from the interface, and it will simulate the circuit as per user requirements and the produced results will be exported. The exported result shall be used by front end applications to display the same. Analyses is done on both the Windows and Linux platforms to check the software reliability. For different analysis the parameter requirements, conditions for analysis and results are documented.

Keywords: planning, load flow analysis, fault analysis, software integration
