随着电力系统的快速发展,电网容量的扩大使其结构更加复杂,实时监控、调度的自动化显得尤为重要。而在电力调度自动化系统中,电力参数的测量是最基本的功能。如何快速、准确地采集各种电力参数是在电力调度自动化系统中首先要解决的问题。 美国模拟器件(AD)公司最新推出了ADμC812单片机,其内包含了高性能的8路12位ADC采集系统、2路12位DAC、80C52MCU内核、8KB的闪速电可擦除程序存储器、640字节的闪速/电可擦除数据存储器、看门狗定时器、电源监视器、I~2C兼容的SPI和标准的UART串行I/O模块及灵活的电源
With the rapid development of power system, the expansion of grid capacity makes its structure more complicated. It is particularly important to automate the monitoring and scheduling of real-time monitoring. In the power dispatching automation system, the measurement of power parameters is the most basic function. How to quickly and accurately collect all kinds of power parameters is the first problem to be solved in the power dispatching automation system. AD Analog Devices (AD) recently introduced ADμC812 microcontroller, which contains a high-performance 8-channel 12-bit ADC acquisition system, two 12-bit DAC, 80C52MCU core, 8KB of Flash erasable program memory, 640 words Flash / EEPROM Data Memory, Watchdog Timer, Power Monitor, I ~ 2C Compatible SPI and Standard UART Serial I / O Modules and Flexible Power Supplies
