Design And Studying Of The Dispatch Automated System Of Electric Power Of Power Administration Of Zhaozhou County

Zhao Zhou lies in the middle of Hei Longjiang , the executive and the electricity-supply are all belong to Da Qing. It is 2455 square kilometer in area and with a population of 425,000. The county is divided into 5 towns, 10 villages and 183 hamlets. In 1999, the total value of production of industry and agriculture in the county is 970 millions. The electrical department is found in the February 1984 and is an enterprise of ownership by the whole people it mainly sells the electrical production, there are 370 workers and has fixed assets about 36.06 millions.With the developing of economic, the electrified wire netting in Zhao Zhou develops fast. It has run 10 main transformers by the end of 1999 and the capacity is 25.800KVA; there are 1233 distributive transformer and capacity is 61650KVA, it has 3 electrical lines which the voltage is 35KV and 26 electrical lines which is 10KV. In 1999 the electrical department supplied 8140KKWH, the largest load is 25.9 thousand kw. It has been more and more important to control the electricity for the fast developing of local economic. The traditional mode has not been adapted to the development. In order to make the net run securely, economically reliably and make the electricity product more economic results, it must be found an modern system of automation, control and provides advantage supervision, strengthen the scientific manage for the net, ensure the security. It is one of the most important works to run economically in today and future. The system of electric control automation in Zhao Zhaou is open, it bases on the net of RS485 bus control and centrally manages substation by control the main machine. The system controls the run parameter of electric equipment and the run environment by using the computer measure, communication and automation technology, it can realize measure, communicate, control and allocate in the remote area, transmit data and control through collect data and automatic count parameter. The system controls centrally and can improve the economic results, used without man. It can find the hidden danger early improve the management of electric system and ensures the secure running. The hardware of system has qualities of collecting and technology of face line, the software uses the model structure. These can make it easy to augment the capacity of system and safeguard and secure.Our design is an intelligent produce which uses electric remote equipment, it can take the place of some relay protection and is used in the substation below 35KV, it correct the trouble which is caused by compact model structure.Academic :Electrization and Automatism of AgricultureCandidate :Yang Jing DongSupervisor :Prof. Qi Guo QiangProf. Wang Qingfa...
