System On Electricity Information Acquisition And Monitoring For Inner Mongolia Electric Power Co. LTD

With the development of society, the rapid growth of electricity consumption,the rapid expansion of the user scale and social power company power put forward higher requirements for measurement, the traditional measurement method mainly rely on manual meter reading meter reading, field staff need to do regular, manual review,analysis, processing of power measurement acquisition hard data, statistical analysis and artificial electric energy measurement is greatly restricted in real-time, accuracy, there is wrong leakage copy of uncertainty, with the information technology development of cloud technology, which can measure electric information, network, provides an excellent platform for intelligent.This paper reviews the research status and deVelopment trend of remote channel monitoring system,makes a detailed study on the critical technologies which applied in the remote channel monitoring system, describes the monitoring system components,functions,and implementation methods of the remote channel monitoring system fom the theory. The designed system achieve the function of acquisition, processing and conversion of remote signals.First of all, make a in-depth study on the data acquisition technology;after several practice tests and validation,design a real-time data acquisition program ultimately,which includ the design of system signal pre-processing circuit,selection of high-speed data acquisition card and the design of associated control software;Secondly,analyse the output signals of end signal pre-processing circuit, study related algorithnls, including the calculation methods of signal level,signal frequency calculation algorithms,the display of real-time waveform and so on, achieve the relevant processing of the signal and the system’s signal processing functions; Finally, because the current remote monitoring system does not have a communication protocol, so make a deep 1earning and study on the protocol converter meter to understand the status of the statutes,grasp the principles of the statute conversion.In this system,use a statute conversion device to converse the statute of the acquisition remote channel signals,then make a further implementation of the communication between remote channel monitoring system and other systems.Finally,system can switch automatically between the multi.channels which are monitored,and can position to a certain analog channels,achieve the real.time extraction and analysis of remote signal waveform, level, frequency and other parameters, complete monitoring3000 road of remote analog channels and displaying real-time data in the user terminal atcenter station.At 1ast,test the monitoring system applied to the field, according to the analysis of the measurement results,the actions of this system designed by the subject are realized basically.This system has the functions such as self-diagnosis, failure can be an alarm, easy to maintenance personnel and so on.
