Research On The Application Aspect Of The Main Control Station Through Time Scalar Measured The Steady-state Data Of Smart Grid

With the development of power grid scale growing,large-scale operation system to further promote the power system put forward higher requirements on the reliability of power supply and power grid safe and stable operation,especially on the operation and control through the remote monitoring personnel can timely find the hidden danger of the equipment,fast processing accident to restore power,even to the electric energy quality control ability put forward a more severe test.As an important tool to ensure the safe operation of power grid,alarm system plays an important role in power grid monitoring.However,the current mode of direct real-time accident exception message,often disturbed substation equipment start or abnormal packet Shuabing at the time of the accident,the accident accident interference message sending station.In addition due to the current measurement data using time scale,resulting in monitoring protected movement and displacement difference switch and other important information and field information protection device for tens of seconds,to control personnel accident judgment and combing accident has brought a huge workload,directly affect the accident disposal.First of all,this paper puts forward the real-time information screening early warning based on scalar measurement,it can appear abnormal when the substation accident interference disturbance information of substation information upload effectively solve the problem of power grid operation,also can solve the alarm single way,jump is difficult to capture the problem of variable measurement.In addition,it can be applied to the scheduling control system of the regional smart grid,and the holographic historical data of the power grid is compared with the real-time data,so as to achieve timely and rapid early warning.To test the scalar holographic accident inversion based,because the time series database gives more powerful data access support section,so the intelligent control station,can make a holographic inversion of all power grid accident.By means of power flow diagram or station diagram and time series accident message,the detailed process of accident can be traced and analyzed,and the process of accident will be visualized.Secondly,in the use of relevant data to improve the accuracy of measuring the scalar grid at the same time,it also brings technical difficulty of a large amount of data processing high,on display and storage time stamped measurements,in the database,no matter which kind of methods,it is difficult to achieve continuous storage when processing the low efficiency problem of scalar measurement;,large amount of data storage and greatly increased the difficulty of the search,let the work become complicated and difficult to operate;with the past real time database and relational database for storing these data can not meet the needs of current.The integrated application of time series database can achieve high precision sampling and record the number of valid time scales in the process.Finally,through the analysis of the application of the steady-state data of the time scalar measurement in the master station of the smart grid,this paper makes a systematic research from two aspects.The first one is to comb the state estimation of the current time scalar measurement,and integrate the time scalar data,the model and the rule effectively,so as to realize the function of timely warning.The second one is the application analysis of open integrated data platform based on time series database..
