Invention Reference Number
Summary
Electrical utility substations are wired with intelligent electronic devices (IEDs), such as protective relays, power meters, and communication switches. Substation engineers commission these IEDs to assess the appropriate measurements for monitoring, control, protection, and communication applications. But the meters and protective relays could measure the phase voltages and currents on buses with different error percentages. This technology provides a method for commissioning test beds of power systems with a real time simulator and hardware in the loop. This technique finds these errors and allows the system to perform the needed corrections based on the power system application.
Description
Electrical utility substations are wired with intelligent electronic devices (IEDs), such as protective relays, power meters, and communication switches. Substation engineers commission these IEDs to assess the appropriate measurements for monitoring, control, protection, and communication applications. Like real electrical utility substations, complex electrical substation grid test beds (ESGTs) need to be assessed for measuring current and voltage signals in monitoring, protection, control (synchro check), and communication applications that are limited by small measurement percentage errors. This technology provides a method for real-time simulators and IEDs in the loop so that protective relays, power meters, and communication devices can be commissioned, and these measured percentage errors could be reduced.
