PC-Based SCADA Simulator for Distribution System Analysis

This paper presents a new PC based simulator for SCADA system which can be used for analysis of distribution networks. The system consists of one PC representing the master station connected through a physical RS 232 link to another PC, which represents the RTU networks. The master station is equipped with all standard SCADA modules such as network analysis functions, data acquisition applications, communication protocols and HMI. The RTU station simulates field data acquisition and data transfer to the master station. It can also respond to any control commands issued by the master station. The paper also presents a new network topology builder, which can efficiently build the network topology based on circuit breaker status. The proposed system has been tested on a test system and shows high performance results.
