Substation Analytics Technical Manual

Overview

COM600 contains two substation analytics applications: fault locator and circuit breaker

condition monitoring. These application operate on data gathered from IEDs on the

substation.

Data is gathered from IEDs in different formats. The measurement data is gathered from

disturbance records in COMTRADE format. This data is added with data reported on

IEC 61850.

Analytics is run on top of this data and published on OffSide OPC server. The results of

the analytics can be mapped onwards to slave protocols such as IEC 104.

The COM600 analytics applications are designed to run on-demand whenever there is

data available from the IEDs which the application needs. For both fault locator and

circuit breaker condition monitoring, there are set of data points that trigger the analytics.

The accuracy of the analytics depends on the accuracy of the input data. The measure-

ments in disturbance records is contains small errors due to measuring accuracy and

decimation done in the IED. This recorded data is then again processed by COM600

which adds another layer of inaccuracy to the results.
