The Design And Realization Of Auto-parallel Device Of Marine High Voltage Power Station

Quasi-synchronizing device as a kind of commonly used automatic device plays a very important role in the operation of the auto-parallel operation in the ship power station. In the modern ship power station, most ship stations adopt microcomputer quasi synchronizing parallel devices. Manual-parallel operation and Simulation-parallel operation are less than quasi-synchronizing device for the superiority of its performance. High performance microcomputer automatic quasi synchronization parallel device not only brings great convenience for the electronic and electrical operation person, but also assures the safety of generator grid ship power system, meanwhile, it reduces the time of generator connect and the waste of energy.So the paper focuses on the design of the microcomputer quasi synchronizing parallel device for the ship’s high voltage power station.The device adapts S7-1200 model PLC as core control device, it adapts modular programming ideas, simple structure, high system integration,what’s more convenient for install.The design of the ship’s high-voltage power station auto parallel device has following functions:1) voltage detection, voltage abnormal alarm;2) frequency detection, frequency adjustment;3) switching control.Auto-parallel device is designing and debugging on the physical simulation platform of the high voltage power station. Through the experimental verification, the auto parallel device is safe and reliable, and the Auto-parallel Operation is effective.
