In a word , this thesis not only expounds the whole structure of stability control of power system based on the theory of control decisions , but also designs software and hardware of sub - control - station , which are different from others . there are several advantages as listed below : 1 ) distributed hardware architecture function modularization realization of communication between modules by high - speed network communication technology ( can ) ( interconnecting 256 modules or mainframes ) flexible , convenient , reliable expansibility of hardware and decreasing system risk . any broken cell only affects local cell 总之，论文不仅在控制策略理论的基础上，阐释了稳定控制系统的整体架构，而且研制设计出新颖的区域稳控子站装置软硬件，其优点体现在： 1 )分布式硬件结构体系功能模块化采用高速网络通信技术( can )实现模块间信息交换(最多支持256个模块及机箱之间的互联)硬件扩展灵活方便、可靠，降低系统风险，任一单元损坏只影响局部2 )实时信息网(控制网)和管理网(监测网)分开。
The design of sub - control - station is modularization . the m16c microprocessor is the processor . the sub - control - station contains modules of communication , generator , line , switch signal input , switch signal output , master and decision , etc . the modules communicate via double can 本文所阐述的子站型的控制装置采用模块化设计思想，硬件是以三菱的m16c芯片为处理器，主要分为通信模块、发电机模块、线路模块、开入、开出、策略机和管理板等等，模块之间通过双can网通信。
The main task of management center is to receive real time data of network from ems , to carry out dynamic stability analysis on forecasting faults , to determine stability control strategies , to modify and generate stability control strategy tables in every main station , and transmit the strategy tables to all sub - stations 管理中心的主要任务是接收ems电网实时数据，对电网预想事故进行动态安全分析，确定安全稳定控制策略，协调、修改并形成各区域主站及子站的安全稳定控制策略表，下发策略表到各主站。
Secondly the need of substation , which is the part of system , and use to collect power data , is given . thirdly the thesis discuss why develop platform of substation is selected and introduce some programming technology used by system . then the main part of system set forth the design and realization of substation system 第三章给出系统子站的需求分析，对于系统子站的设计，论文分别用数据流向、事务组成、模块组成等三个角度、层次来分析子站软件，循序渐进使子站软件具体化，并把子站软件划分为五个模块。
Nowadays , the national lightning detection networks have been set up in developed countries . the national important project - atmosphere automatic observation engineering is about to start in china . the first - term project of national lightning detection network , which consists of 90 lightning location stations in meteorological branch , will be finished at the end of 2003 地闪定位系统在几个发达国家已全国联网，我们国家重点工程项目“大气监测自动化系统工程”即将启动，其一期工程就是在2003年底将建立拥有90个闪电探测子站的全国闪电监测网。
According to the design request , the hardware system structure for reasonable sub control center is worked out , and the real - time operating system is chosen , for which suits the sub control center ' s function demand ; meanwhile synthetically analyzes the application characteristics of the sub control center according to the function and position in the electric automation system , together with the function demand and application target of the applied software 根据配电子站的性能要求，设计出了合理的配电子站硬件系统结构，选出了适合配电子站功能需求的实时操作系统；同时根据配电子站在配电自动化系统中的作用和地位，综合分析了配电子站的应用特点，给出了其应用软件的功能需求和其应用指标。
The automation is composed of two operating station computers ( one is a backup computer ) and three slave computers . every slave computer , which is cored by omron c200 plc , controls a generator independently . slave computers have data detection and control function with the help of the data detection and control interfaces which are composed of all kinds of position swiches , sensors and execution units 本自动化系统由两个主站(其中一个是备用站)和三个子站组成，每个子站由一台omronc200hplc构成，独立控制一台发电机。
In succession , contraposing the 101 protocol and dl / t 645 protocol , using msp430 chip fufills the devise of the converter . in software designing , completes the devise of 101 protocol substation part and the master part of 645 protocol , realization communicating between the two protocols . based on it we expands some functions to make the converter possess the fuction of data handle and data saving such as possessed by the commonly remote terminal units 接着，针对101规约和国标dl t645多功能电能表规约这两种不同通信协议，运用msp430芯片设计了电力监控转发器。在监控转发器的软件设计中完成了101规约的子站部分设计和电能表规约的主站部分设计，实现了这两种协议间的信息传递，并在此基础上做了适当的功能扩展，让监控转发器具备了一般远方终端所具备的数据处理和数据保存等功能。
The communication scheme from the automation terminal equipment to substations has been carefully selected . so it is a favorate plan with high performance - cost ratio . the implementation of the scheme will greatly enhance the automation level in huhehaote urban distribution system 本文所提出的配电通信系统设计方案充分考虑了利用现有调度自动化通信系统，合理选择自动化终端设备到子站的通信方式，是一个性价比较高的混合通信设计方案，该方案实施后，将大大提高呼和浩特城区配网自动化水平。
