Distribution Of The Integrated Monitoring And Reactive Vr System Research And Development

As the increase of the power consumption, power supply quality becomes the focus that people pay close attention to day by day. The quality of power supply can be decided by monitoring the operation state of the low-voltage distribution transformer. But the automatic degree of monitoring is not high at present. In some places the transformer is overloaded, and thus causes accident, the phenomenon of sneaking current often happens, the power consumption is not forecasted, and accident cannot be reported in time, it leads to a power failure and unnecessary losses of the power supply company.Firstly, this thesis explains the development, objective, function, content and the necessity of exploiting the distribution transformer monitoring system, the construction and function of this system is also put forward.Power loss of distribution network accounts for the major part in the total loss of power network. Therefore, it is necessary for reactive power compensation to be adopted to decrease the loss of power distribution network. After the technological and economic comparison among concentrated compensation, respective compensation and transformer compensation, the transformer compensation is taken.Secondly, combined with the feature of distribution network management and operation of power supply enterprise, this thesis proposes the tactics, principle, objective for developing the distribution transformer monitoring system. On the basis of the latest achievements of computer technology, a distributed system method to construct the supervisory system for distribution transformer is presented, the main functions of system are summarized by discussing with the users many times, the system and database are also designed and optimized.Lastly, a practical system developed based on the theory mentioned above is introduced, from requirement analysis, deciding the system objective to database design, function realization, embodying the development tactic and Client/Server design approach.The distribution monitoring and reactive power compensation system may become an independent automation system. It can take shape and supplement to the distribution SCADA system, and make data shared resources for the distribution management information system, user service system, etc. Practice has proved that the system functions perfectly, easy to use, totally satisfies the actual demand, and it can improve the management level of power supply enterprise.
