March 2014 Issue
These changes require a fresh look at what the protection, automation and control industry is doing to ensure power system security. We are not talking about the ability of the system to withstand cyber security attacks. We are talking about the ability of the electric power system to withstand contingencies without significant impact on customers and the stability of the system. For many people ... More

Design of System Integrity Protection Schemes (SIPS)

Considering the importance of SIPS to the stability of the power system, the IEEE PES Power Systems Relaying Committee WG C15 published a report “Design and Testing of Selected System Integrity Protection Schemes (SIPS) .“ The design of SIPS varies from scheme to scheme and is very different from the design of conventional protection systems. It even varies from application to appl... More

IEC 61850 Update

Where are we today with IEC 61850?

Now, ten years later, where are we with IEC 61850? I would estimate that in the meantime more than 5,000 substations worldwide are equipped with IEC 61850. So obviously, IEC 61850 can be considered as a well-established standard. While I was visiting DistribuTECH in January, I learned from a US utility that it had recently successfully commissioned its first IEC 61850 substation - on their own - n... More

Lessons Learned

Global SIPS Experience

Local protection systems arrest the propagation of the fast-developing emergencies through automatic actions and are applied to address equipment specific or local system problems. Local protection systems are not engineered to address large-scale power system problems, or to arrest the system from large scale cascading events. The trend in power system planning is to develop tight operating mar... More


SIPS in the Colombian Interconnected Power System ? System Integrity Protection Schemes

These actions are part of the Defense Plans aimed at preserving the electric power system reliability of any country.

Defense ... More

SIPS Testing

Functional Testing of System Integrity Protection Schemes

Misoperations under non-critical system conditions may also result in the unnecessary tripping of multiple loads, in both cases leading to economic losses. That is why it is so important to ensure the correct operation of SIPS using proper testing and monitoring methods and technologies. Functional and application testing is the most widely accepted testing practice for protection and control s... More
