Distribution Automation Kyushu, Japan
. d. Finally,[link widoczny dla zalogowanych], the computer quickly and accurately narrow the power range for the load optimization, to complete the load side of the interval of non-fault power supply automatically transfer deal. 3.2.2 Substation Fault Treatment failure in the substation (substation transformer outage or failure full stop) case, the general time under the power failure is classified into two kinds. a. Less than 1min power substation to restore power immediately after the closing instructions from the computer sends the same time, followed by the power supply side in the closing operation of the switch. b. Computer power for more than 1min power wire range of fully equipped to implement the optimal load transfer of power; In addition, the process of transfer of power, such as power substations have been restored, the computer will not constitute a loop in the implementation of re-operation of distribution network After issuing the command while Taiwan gate. Since the application of this system, so that when the power failure about the time application in the substation before the 1/lo; distribution line fault in the application of the former is about 1 / 20.4 the current status and future technology development measures 4.1 wide ws System used by the control system of the whole WS WS (commonly used,[link widoczny dla zalogowanych], standby), and console WS (shared table, console), and the remote control between devices using WS LAN (control system LAN) and control inter-WS and WS console the LAN (that line LAN) composition. Console can be remote from the operation and offline business (maintenance) of the common units and remote control function only together constitute the console to achieve a unified database to reduce the console WS main memory and disk capacity. 4.2 Distribution of general business use the full WS system greatly improved processing capabilities, large database systems in addition to automatic control outside the normal distribution can also be used for business planning functions such as equipment, low computing power line loss system , fault simulation capabilities, making high-pressure single-line diagram capabilities. While reducing equipment investment, improve business efficiency. 4.3 multi-function switch, FTU the development and introduction of now, the voltage distribution line substation outgoing load management is based on the voltage, current and power factor to carry out, so due to the special load (high users of capacitive reactive power compensation, etc.) increases, the only outlet to rely on remote substation to the sound management of voltage value becomes very difficult in the distribution line fault, reclosing is successful, although the full range of inspections to be carried out to confirm the cause of fault and fault,[link widoczny dla zalogowanych], but not necessarily able to find cause of the malfunction, so that the inspections will take a lot of energy. Therefore, in order to achieve in the future to improve the accuracy of the voltage and load management, early identification of failure interval such purposes, to reduce costs, improve business efficiency as the goal, in 1999, can be developed and introduced a variety of data measurement (voltage, current, power factor , fault information, etc.) Built-in multi-function switches and sensors to send the measurement data of the FTU. Revelation 5 With the deepening of the power system, establish a good corporate image, enhance service awareness has become essential to the development of their own power means, therefore, the progressive realization of distribution automation, to provide users with reliable electricity, is in a period of important work. Through research, the following revelation to us. a. Means to ensure that the user depends on the reliability of distribution network automation and live 10kV Xitong operations carried out. With Jilin Electric Power Co., Ltd. Chengwanggaizao works, the city distribution network A frame structure is more reasonable level of equipment is the rapid increase has taken with the conditions for the realization of distribution automation, power distribution automation should be achieved as the \during \b. In the current network reform process should be based on current and long, with network design standards and technical principles should take into account the favorable development of distribution automation. If the transformation when the load between the 10kV line, phase deployment platform manager, the line with a capacity between the switch with each other; improve the switch number and the relevant basic data,[link widoczny dla zalogowanych], drawings and so on. c. Distribution network construction in the same time, should be designed to facilitate the carrying out live working as a principle. Domestic relatively rapid development of distribution automation, and more functions, power distribution SCADA systems, power failure detection and diagnosis, recovery and distribution application software (DAS) systems, automated mapping (AM), distribution facilities management (FM), and geographic information systems (GIS), software features more perfect, but some features used in the actual application process less, to the user but also brings high requirements, testing process is also more chance of problems, so,[link widoczny dla zalogowanych], using The system should have the necessary key features, other features should be the main industry and sector division of responsibilities, development of the corresponding function. -= Guo cans. . .
