Abstract


Power system substation geographical distribution is very wide , far apart , remote monitoring plays an important role . Dispersed unattended site , you need to regular collection of data , in order to keep abreast of the situation of the scene , and send control commands according to the situation . With the development of wireless communication technology , the traditional way to achieve remote monitoring system and the high maintenance costs , has been unable to fully meet the requirements of certain aspects of the use of wireless communication data transmission media as a power monitoring system has a broad prospect . Xinglin Bridge power monitoring system developed and compared several characteristics of communication technology , a GPRS-based wireless remote monitoring system , and made ??some of its exploration and study design . The main work of this paper are as follows : (1 ) a brief introduction to the characteristics of the power system , on the history of the development of China 's electricity monitoring technology . Introduce the power monitoring system \Various communication technologies compare electricity monitoring system proposed based GPRS network communication architecture , and its feasibility and advantages . Wireless communication network based on GPRS-Internet the network APN Dedicated compared to analyze the advantages of the latter . ( 2 ) the overall architecture of the monitoring system , the monitoring center software design . Monitoring master software system constituted by the three levels of the data layer , business layer and application layer , the main system management , view management (including information table , the current graph ) , parameter setting , record query . The system uses ADO.NET database connectivity technologies . The paper lists the details of the the CDT protocol , data packets analysis process . ( 3 ) combined with the actual situation , listed several conditions that may exist in the monitoring system , do a detailed description of the cable fault alarm monitoring system and current -limit alarm mechanism . Finally, the failure prediction techniques discussed . Failure prediction technology based on the ARMA model , while monitoring the real-time data to do the simulation analysis .
