| Abstract:ABSTRACT： The grid monitoring controller which uses the traditional differential linear combination control method and is connected through the PLC and executive component and data acquisition is used to monitor the faults of the separate units， but the result is not good enough. In view of this issue， this paper proposes the design of a grid intelligent monitoring DCS （distributed control systems）controller based on the small PLC. With this method， the grid intelligent monitoring system model is constructed， the acquisition algorithm of fault feature signals in the monitoring is designed， and the small PLC programmable logic controller is used to design the DCS grid intelligent monitoring decentralized controller and the key circuit module. The corresponding simulation results show that the controller designed with the method proposed in the paper has satisfactory power system fault data acquisition， low fault detection error， high control precision as well as good stability， and it also has higher convergence speed， and can effectively guarantee the real-time and accuracy of the power grid monitoring. |
