| At present, the reconstruction of city power net has made many opportunities for the distribution automation technology and it's reliability. Hence, the power supply companies of all levels should accelerate the construction of power net and distribution automation system in the coming times, so as to improve the quality and reliability of power supply, to meet the demand of power supply for the modernization construct .Currently, there are many factories who can made distribution automation facilities in our country, there are some differences between their technology. Although many power supply companies are making reconstruction for the distribution automatic, some needed criterions are still lacked. Some representative cases of other countries are difficult to coincidence with our countries need, the pilot unities build in the early time are restricted by the technology of that time. Currently, there are there popular modes for the main station of distribution automation in our country. They are windows operation system , UNIX+Windows mixed operation system and full UNIX operation system. For the UNIX+Windows mixed operation system, it has some advantages such as good stability and reliability for system operation , high speed for data analyse and low engross percentage of network.This thesis is based on the use of distribution automation system in Doumen Zhuhai power supply company. In the practical use, summarize technology data , compile code, test and operate in that local ,these operation are made. This thesis gives an detailed conclusion for the main station used UNIX+Windows mixed operation system in these aspects :system frame, function implemention, software compose, data analyze process and difficulty solution .Two representational block are chosen, they are the network and task management block and the real time data processing block. The technical character of the UNIX+Windows mixed operation system are exhibited in the thesis in these aspect:element realization ,main technology application, flow operation and code realization.The distribution automation main station used UNIX+Windows mixed operation system talked in this thesis has been used in Doumen Power Supply company for a long time. Datas from the practical test and compariation with other systems also can prove the advantage of this system.All this above proved that the theory about bottom technical realization researched in this thesis is feasible .This thesis also gives an example for reference for other similar platform. |
