Abstract


Safe and stable unit 's goal is to ensure that the accident state power grid security and stability , reliable , real-time communication scheme is to achieve stability control and stability control device capabilities powerful guarantee ; sampling data accuracy and rapidity of action is to determine the stability control means an important indicator of quality , power system stability control requirements means faster decision-making and control , security and stability control devices require high-speed, reliable communications systems and data acquisition systems. This paper first reviews the security and stability control device analyzes the communication system and data acquisition systems research status , trends and significance of the study . Then combined with the security and stability of their own characteristics and control device requirements, design a communication scheme based on optical fiber communication . First analysis of the overall communication scheme hardware design and implementation process ; Secondly communication schemes were tested and analyzed , the test results show that the communication scheme is stable , reliable , high-speed operation ; once again the communication system needs further study analyzed, and the communication system research and design are summarized. The communication system has been put into the field of operation. Secondly, security and stability control device data acquisition system designed two programs and two programs are compared , the final selection is based on SOPC (System on Programming Chip) technology for high-speed data acquisition system design. Analysis of the data acquisition hardware solution implementation process for FPGA (Field Programmable Gate Array) design process presents two designs : the use of VHDL (VHSIC Hardware Description Language) language and use SOPC technology. The data acquisition system hardware and software tests show that the data acquisition system can be stable, accurate , high-speed access to the external input analog multiplexer The final conversion result .
