Abstract


With the rapid development of computer technology, power electronics technology , more and more in a variety of smart devices used in substations , especially high - voltage substation , a variety of smart devices has been widely used , has introduced new substation automation mode the traditional RTU mode is increasingly not suited to today 's power monitoring system requirements, power system monitoring and control devices is moving in the direction of the development of object-oriented and combines many functions in one , not only as a monitoring and control devices in the traditional sense , but a information collection and processing center. In this paper, the development of new high - voltage substation monitoring and control device for the purpose of a comprehensive summary of the present situation and development direction of the current high-voltage substation monitoring and control device , system analysis the principle of substation monitoring and control devices and related new technologies . High voltage substation monitoring and control devices of a variety of new functional requirements, and proposed the corresponding solution and implementation of programs . Large number of applications in the new device is designed to fully adopt international standards in a number of new technologies , monitoring and control devices , software and hardware design and development , the openness of the device can be guaranteed , the reliability of the monitoring and control devices at the same time a solution , fully meet the future substation requirements. All smart devices in the station data in the monitoring and control devices to be integrated , so that all users need to be utilized , substation automation solutions enhanced by increasing improve the applicability and ultimately reduce the user cost of many new features . A variety of useful new features are integrated in a single measurement and control devices , including appropriate programmable program controller , substation LAN node , the gateway of a variety of smart devices , energy metering , power quality monitoring , fault recorder . The monitoring and control devices can also be flexible in large - scale distributed substation composition set , measurement , control , equipment management , communications integration and control system , after various hardware and software functional testing , the results show that the new monitoring and control devices of the technical indicators fully met the design requirements .
