A Real-Time Digital Solver for Smart Substation Based on Orders

Abstract

In order to expand the simulation scale of smart substation, a simulation model of the inlet-outlet line unit, as described by the 0/108 S conductance for multivalued coefficients pre-storage is presented in this paper. As a part of orders decomposition, the address conversion circuit for multivalued coefficients can reduce the computational burden of processing elements. For the convenience of the generalization of the real-time digital solver based on FPGA (FRTDS, FPGA: Field–Programmable Gate Array), the address conversion circuit for multivalued coefficients is matched with the guide word, the formation module of sampled value (SV) packet, and the resolution module of generic object oriented substation event (GOOSE) packet are associated with the application identification (APPID) in the Ethernet frame. The address conversion circuit for multivalued coefficients, the formation module of SV packet, and the resolution module of GOOSE packet are reconstructed via the orders. A hardware-in-the-loop real-time simulation platform for smart substation is built based on the novel FRTDS. A case is given to demonstrate the simulation calculating capability and the hardware-in-the-loop ability of the novel FRTDS.
