Design of Low Voltage Protection Device Integrated with Measurement and Control Function Based on Power Dedicated Multi-Core Heterogeneous Chip Architecture

This paper presents a hardware and software design scheme of a low voltage relay protection device integrated with measurement and control based on power dedicated multi-core heterogeneous chip. Combining with the basic structure of power dedicated multi-core heterogeneous chip, this paper describes the overall design of highly integrated low-voltage protection device integrated with measurement and control;designs the external interface of hardware for low-voltage all-in-one and standby self-switching devices;expounds the design of software system architecture and the allocation of device functions among multi-cores, focusing on power dedicated algorithm, real-time data flow based on pre-data processing and calculation of electrical parameters, and the abstraction of peripheral device access. The optimized multi-core communication mechanism is analyzed. Function and performance of the low-voltage protection device integrated with measurement and control based on the chip has been verified at the low- voltage side of a 110 kV substation, and the feasibility of the scheme is verified by the test results.
