Title The hardware design of the power system comprehensive measurement and control mechanism
Abstract
With the rapid development of China's economy and society, computer technology and power electronic technology are becoming the mainstream of the era of the development. Power system measurement and control device are also moving in complete functions, stable performance, quickly operatation direction, so in a powerful system was not only the traditional measurement and control device, but also collecting information and the integration center. Therefore, the hardware design of the measurement and control device is also the key topic for the comprehensive measurement and controlling device of the power system.
In the design of integrated measurement and control equipment of power system, the system needs the main CPU part, storage, AD converter, part of CAN bus and clock circuit part of the design and analysis. Understood the main function of the main CPU and the types of selection, designed the reliable high performance memory, fast operation and AD converter, a high degree of accuracy and specific sampling function achievement is the most important. Completed outside the analog signal is sampled, and carries on the analysis and sorting through the AD converter input for CPU, putting into memory in order to save, and then CPU can output the messages to the host computer. The hardware of the design is the standard for measuring and controlling device of modern power system.
Keywords Measurement and control system、Hardware、Reliability、Flexibility
