Real Time Monitoring of OT Devices Through INMS

Tata Power-DDL is a front-runner utility in implementing new technologies in order to improve quality of service to its consumers and enhance consumer delight from time to time. Tata Power-DDL has been successfully managing its power grids remotely. As we are aware that technology plays an important role in increasing the efficiency of our electrical network system, hence to increase the reliability and efficiency of our electrical network system we have automate our network along with real time control on OT devices. In view of this we need a system by which can enable us to monitor the real time availability of the Operational devices like RTUs, FRTUs IEDs etc. which are used to operate the electrical network remotely. To achieve this we propose to implement an integrated system called INMS (Integrated Network Management System) which will enable the utilities to monitor the real time availability and performance of all OT devices. In this paper we are focusing on mainly two issues that is (A.) How we will monitor OT devices on real time basis (B.) What would be the benefits of implementing INMS in a Power Utility? With the help of INMS we are able to monitor the availability and performance of our large electrical network devices on real time basis. It automatically detects faults of electrical network devices through periodic polling of each devices and generate alerts if it is unable to communicate with that device. INMS gives us a complete monitoring solution with following capabilities: (a) Fault monitoring, (b) Alerting, (c) Topology discovery, (d) Performance monitoring.
