Power System Network Simulator (PSNsim)

Transcription

1 The PSNsim is hardware simulator that simulates all parts of power system from generation to utilization. The PSNsim is a scaled down model of the real power system that provides an experimental environment where motivated students, researchers can learn and gain piratical experience in the domain of power system. PSNsim Lab is a dedicated space equipped with state-of-the-art power system devices such as Generators, Wind turbines, Solar PV, transformers, transmission line models, distribution networks, consumer loads, protection relays, automation system, monitoring and control system, communication networks and advanced software. This is to enhance faculty and students research and learning experience in electrical power industry by providing dedicated lab to conduct research activities and projects. The objective of the PSNsim is to conduct the following research activities Power system control and operation Renewable energy Smart grid Power electronics SCADA and automation Distribution Management System Power Quality Analysis Energy Management System Power System optimization Protection and rely coordination Deregulated energy market Communication Network Architecture and protocols Power system analysis, dynamics, computation, economics, transmission and distribution A PSNsim is based on six modules Generation Module Substation Module Transmission Module Distribution Module SCADA Module Control Center Module Individula modules specified in this catalogue, can also be delivered on request. Warrenty is valid 12 months from delivery. The waranty covers repair or exchange of defective parts, due to faulty design. 1
