Research of programmable logic microprocessor-based protection based on Matlab

目前在低压微机保护装置中,基于可编程逻辑的微机保护的应用是越来越多。这种微机保护平台,提高了微机保护装置的可靠性、灵活性、实用性、可扩展性和可移植性,大大缩短了产品的开发周期,同时有效解决了微机保护装置的工程化问题。在分析了目前常见的可编程逻辑微机保护之后,提出了一种新的基于Matlab/Simulink工具软件和DSP相结合的可编程逻辑微机保护的设想,这种方法预期有更高的灵活性,更短的产品开发周期。

In the current Jow-voltage microprocessor-based protection devices, those microprocessor-based protective devices are more and more based on the application of programmable logic. This microprocessor-based protection platform will enhance the microprocessor-based protective devices＇ reliability, flexibility, practicality, scalability and portability, greatly shorten the product development cycle, while can solve the engineering problems of microprocessor-based protective devices. Based on the analysis of the current common programmable logics of microprocessor-based protection, this paper proposes a new method of programmable logic microprocessor-based protection based on Matlab / Simulink tools and DSP, this method will have higher flexibility, shorter product development cycle.
