摘要
开发了一种基于数字信号处理器与控制器局域网络总线的井下采区变电所无人值守综合自动化系统,实现了采区变电站的无人值守。系统由监控中心、通信接口和智能测控保护单元组成。重点研究了智能测控保护单元部分软硬件设计和测控保护算法;针对井下采区变电站的实际应用环境,设计了适合井下供电系统的测控部分模拟量交流采样算法和微机保护算法,以提高测量精度,实现及时有效的保护。
A new kind of integrated automation system was designed based on digital signal processor and CAN bus, the unattended in mining area was realized in the paper. The system was composed of the monitoring center, the communication interface and,the intelligent supervision and protection units. The authors focused attention on the design of hardware and software of intelligent supervision and protection units,and the algorithm of supervision and protection. According to the actual environment in mining area, the authors developed a supervision and protection algorithm suitable to the exchange and sampling of analog quantity of supervision and protection units in power supply system underground and the algorithm of microcomputer protection,improving the measuring precision and realing the effective protection in time.
