Introduction
SINCE THE INTRODUCTION OF DIGITAL RELAYS,
it became evident that test procedures adopted by the industry
in the early days of relay testing needed to be adapted. The
cause of misoperations was no longer related to mechanical
failures or drifts in the relay components, but mostly related
to logic, settings, or design errors as the last editions of the
North American Electric Reliability Corporation misoperations
studies consistently shows.
Settings-based testing approaches to calibrate electromechanical
relays or identify relay failures were becoming less
important. System-based testing approaches started to get traction,
especially for applications like end-to-end testing of communication-assisted
protection schemes. For a system-based
approach, test cases are derived from a power system simulation
of real-world fault scenarios. With this approach, not only relay
failures can be found but also setting calculation errors, logic
misconfigurations, or communication-related issues. This article,
which was presented at the 2021 Western Protective Relay
Conference, will describe system-based protection testing.
In IEC 61850 digital substations, the advantages of systembased
testing are even more obvious considering the distributed
ieeepower & energy magazine
nature of typical digital substation designs. One advantage is
that only the system topology (model of the system under test)
and the system configuration language (SCL) files defining
the communication behavior are needed to build up the test.
No specific information from the intelligent electronic device
(IED) settings is required. A system-based approach should
allow for modular testing under different testing conditions.
The system can either be tested entirely or divided into subsystems,
where testing of the subsystems would contemplate some
level of overlapping. Protection testing can be performed with
a subset of IEDs by simulating the merging units (i.e., sampled
values), while the current transformers (CT) and voltage transformers
(VT) measurement circuits can be tested as a separate
subsystem. This allows for a high level of flexibility during
commissioning and maintenance.
Digital Substation Architecture
IEC 61850 concepts and protocols have enabled the implementation
of digital substations. As described in " Remote
Testing of Protection Devices and Schemes-Principles,
Applications, and Benefits, " digital substations are the ones
where all interfaces between the process, IEDs, supervisory
