Grid monitoring tool — A case study of ERLDC, Kolkata

To improve the response time of the system operator, a robust monitoring system is recommended. Design of such system is done so as to impart additional intelligence to the conventional monitoring system by creating logical analytics, using abnormality / limit violation of important parameters such as frequency, flow gate limits etc. or using combination of two or more such parameters. Further, the output of such logical tests / analytics may be monitored periodically and alerts may be generated for violation of preset values of any of the tests. Such a system may be utilized to alert relevant functional groups other than grid operator viz. reliability coordinator, market operation group etc.
