Design and Development of a Novel Integrated On-line Monitoring IED for High Voltage Switchgear
Traditional on-line monitoring IEDs for high voltage switchgear have many disadvantages
e.g.too many configuration models
high failure rate
high fake alarm rate and high engineering cost.In order to solve the issues
a novel integrated and low cost on-line monitoring IED for high switchgear is put forward in this paper.The integrated IED is based on mature hardware and software platform of protection and control devices in substation.The integrated IED is developed on module and distributed architecture.It integrates the functions of many traditional monitoring devices
e.g.mechanical characteristics
SF6 and PD.It reduces the engineering cost and failure rate.The integrated IED can give the comprehensive analysis report based on multiple types of data.It improves the correct rate of alarm significantly compared to the traditional monitoring devices.The integrated IED has been mounted on the GIS.The test results show that the integrated IED meets the requirements of condition monitoring of high voltage switchgear.It can be widely used in projects.
