Seminar Description

This tutorial-cum-workshop will have about 1½ day in-depth tutorial on principles of generator protection and about ½ day hands-on workshop on calculating generator protection settings.  In generator protection applications, excessive fault currents with a large X/R ratio, tending to saturate Current Transformers (CT), are expected. Thus CT accuracy class has a significant impact on protection performance and even on what type of protection should be applied. The tutorial will discuss CT accuracy requirements and a tool for evaluating the CT performance in these applications. In the workshop, an illustrative example from a real life application will be used to show how multifunction digital relay can be used to enhance protection reliability. Relay disturbance records will be reviewed to demonstrate that their analysis leads to an improved understanding of equipment characteristics and thereby its protection. Since digital relays offer logic functionality, a brief discussion will be presented on how this internal logic can be used to develop standardized design templates for equipment protection. The standard template leads to increased efficiency, reduced design cycle, improvements in reliability, minimized inventory of maintenance spares and better management of relay settings. 

In summary the tutorial will cover the following specific topics:

• In-depth review of generator protection including trip sequences.
• Demonstration of a spreadsheet based IEEE/PSRC CT saturation program with author’s enhancements for assessing protection performance under CT saturation conditions.
• Hands-on workshop involving calculation of settings for protecting large generator using with multifunction digital relays.
• Review of fault records captured by the digital relays in response to actual faults or mis-operations.
• Standard design approach afforded by multifunction digital relays.

** Note: Please bring a calculator to the session.
