On Line Monitoring of Higher Rated Alternator using Automated Generator Capability Curve Administer

Abstract

On Line Monitoring of Higher Rated Alternator of 30MW and above capacity using Automated Generator Capability Curve Administer provides the correct operating regions of the Alternator. By giving the Alternator ratings from the design data, the Administer draws the Capability curve for the given Alternator by using MATLAB program. The operating point of the running Alternator is also drawn in the Capability curve after giving the Voltage and Current inputs from Potential Transformer and Current Transformer respectively. The running Alternator parameters are calculated from the characteristics of the Capability curve by using MATLAB program and display all the parameters of the running Alternator including its Field Current and Load Angle which are not being measured in the conventional metering system used.
