Abstract
First,this paper introduces the current situation of using CAN controller in relay protection device,mean-while,if making FPGA as the main control chip,the practical problems and potential risks of using CAN controller put di-rectly into relay protection device will be analyzed.In addition,this paper proposes an optimized plan that can adapt to high-speed communication interface and be compatible with multiple communication protocols.The feasibility of the scheme is an-alyzed,and the design idea of the two-step CAN controller is handled.One of its advantages is that the bus arbitration of CAN controller is customized and postponed to reduce the risk of error action and rejection action.Another advantage is that the frame loss and the metastable risk will be eliminated by partition-control and isolated communication.It has certain refer-ence value for the design and application of CAN controller in relay protection device.关键词
