Continuous Monitoring of Smart Grid Devices Through Multi Protocol Label Switching

Abstract

Data refreshment rate of a present power system is relatively slow and in some cases this slow refreshment rate may not be capable of providing information about dynamic state of power system devices. The use of multi protocol label switching based technique is one option to overcome this problem. A cost effective and simpler detection device is needed for condition monitoring and integrating the sensor signals into the smart grid monitoring system. Remote and on-line monitoring of ultra wide band partial discharge signal in a switch-yard is a new concept in smart grid technology that will help avoid damage of switchyard devices. It is possible to convert the radio frequency partial discharge signal into an equivalent milli-volt or milli-ampere output for remote or centralized monitoring of switchyard devices. Multi Protocol Label Switching based data transfer rate is faster than the conventional data transfer system of a power grid. In this paper a new and technically better method of on-line radio frequency partial discharge monitoring from a remote smart grid control room through multi protocol label switching is discussed.
