Title:
APPARATUS AND METHOD FOR ENSURING RELIABILITY OF PROTECTION TRIP OF INTELLIGENT SUBSTATION
Document Type and Number:
WIPO Patent Application WO/2017/101238
Kind Code:
A1
Abstract:
An apparatus and method for ensuring the reliability of a protection trip of an intelligent substation. The apparatus comprises a main CPU and an auxiliary CPU connected together, and a main FPGA and an auxiliary FPGA connected together, wherein the main FPGA and the auxiliary FPGA are both connected to a physical layer of a protection apparatus, and the main CPU and the auxiliary CPU are both connected to a state monitoring data output end of a protected device. The method comprises: the main CPU sending a processing result to the main FPGA, the auxiliary CPU sending the processing result to the auxiliary FPGA, and the auxiliary FPGA synchronizing current information with the main FPGA after receiving information sent by the auxiliary CPU; and when the main FPGA receives trip information, the main FPGA comparing the consistency of current trip information obtained from the main CPU with that of current trip information obtained from the auxiliary FPGA, and if the two are consistent, the main FPGA sending the information received from the main CPU to the protection apparatus, otherwise, discarding the information received from the main CPU. According to the present invention, an anti-misoperation ability of a protection apparatus is improved, and it is ensured that the apparatus cannot cause a false motion of a primary device due to an unknown error where a hardware device, single event upset (SEU), etc. fails.
