Abstract

The present invention relates to a monitoring and directing method based on a ship distribution of PSCAD and PLC, which is characterized in that: the PLC controls a distribution device and gathers a signal, the PLC by an Ethernet receives the information of a monitoring station and a directing station and receives a control signal of the monitoring station in the condition of remote control; the monitoring station monitors the distribution device based on a WinCC configuration software, the directing station performs an operation simulation for distribution network based on a PSCAD power system simulation software; a PSCAD interface module is built which includes a switch state input module and a data output module, wherein the switch state input module is used in the directing station to call the electrical switch status signal of the monitoring station, and the data output module is used for interacting a distribution network information between the monitoring station and the directing station, namely the data between WinCC and PSCAD are interacted to realize a dynamic simulation.

Description

technical field [0001] The invention relates to a method for monitoring and directing ship power distribution based on PSCAD and PLC. Background technique [0002] The degree of electrification of modern ships is getting higher and higher, and the dependence on power supply is getting stronger and stronger. Therefore, the power system has become one of the indispensable and important systems of modern ships. The power supply of the equipment must maintain a high quality of power supply under the conditions of complex and changing working conditions. The requirements for the continuity of the power supply of the ship's power distribution system are also getting higher and higher. The requirement for the protection device of the ship's power distribution system is to be able to safely break the overcurrent caused by faults such as short circuits, and at the same time make the scope of the accident as small as possible. Especially for important loads in the ship, the continuit...
