把分布式电源作为一个可控负荷,通过设计新型嵌入式管理终端,将传统的电力负荷管理终端和新的分布式电源监控相结合,把分布式电源纳入配电网自动化系统的负荷管理,并实现分布式电源和负荷的本地监控。设计并完成嵌入式管理终端和本地监控中心的软硬件开发:接入点测控单元以DSP TMS320F2407为核心,实现对接入点的遥测、遥信、遥控、网络通信等功能;嵌入式管理终端以AT91RM9200处理器为核心,包括下层通信、上层通信、负荷管理、远方抄表、电能量分析、发电管理、分布式电源接入点管理等功能模块;本地监控中心软件分为前置处理、实时数据服务、历史数据库以及人机交互界面。通过搭建实验测试平台证明该系统满足可靠、规范的通信、控制管理,与现有系统兼容等需求。
An embedded management terminal is designed,which regards the distributed generation as controllable load to integrate the distributed generation into load management of distribution automation system and realize local for supervision of distributed generation and load. The software and hardware of embedded management terminal and local control centre are developed. The data acquisition and control unit takes DSP TMS320LF2407 as its main processor to accomplish remote metering,remote signaling,remote control,network communication,and so On. The embedded management terminal takes AT91RM9200 as its main processor to accomplish communication,load management,remote metering,power energy analysis,generation management,and so on. The local control centre software is comprised of front-end processing,real- time data service,history database and human- machine interface. A test platform is established and the test results verify that the design meets the demands of reliable and normative communication,control and management,being compatible with existent system.
