Because today’s industrial control systems are networked more than ever before, there are new risks that threaten control system availability and security. Whether it’s a malicious attack, Stuxnet1-like worm or an unintentional security breach, such as an employee opening an infected file, the potential impact of such an incident could lead to endangerment of public or employee safety, loss of production, violation of regulatory requirements, harm to the environment and equipment damage. Having a well-defined cyber security strategy can help mitigate the risk of employee or system error as well as aimed attacks. This presentation will focus on outlining and discussing essential cyber security measures and features in the field of substation automation.

Using IEC 61850 standardized semantic models for disturbance recording, autoreclosing and protection trip conditioning functions offers an advantage for creating interoperable distributed protection and control solution. Mapping the semantic model objects to fast GOOSE messages for status and control purpose satisfies strict functional and time performance requirements. The presentation will describe the IEC 61850 architecture, services and data objects for the proposed solution and will provide several practical examples based on the real fault data.

Over four years ago, realizing that protection and control were melding together, PSRC officers approached the PES Technical Council with a proposal to combine the C0 Subcommittee on Data Acquisition, Processing & Control Systems with PSRC H Communications Subcommittee. This started an entire PES Technical Council reorganization effort that has been put in place and is commencing at the July 2016 PES General Meeting. This presentation will address what is the reorganization, what has changed, and how this organization effects the protection and control standardization process.

This presentation will review the subsynchronous oscillation phenomena and the interactions between the electrical power system and the mechanical turbine generator system. It describes subsynchronous oscillation detection algorithms and special filters’ designs, and presents an application that combines subsynchronous oscillations detections with synchrophasors streaming. Finally, some results will be given showing the applications, simulation results and field experience in several power systems.

Expensive, and in many cases unrepairable, ruptures of power transformer tanks are caused by lengthy clearing of internal faults which can be avoided with the choice of the correct protection algorithm. Insulation of power transformer winding can break down at any time, causing significant ground fault current, especially in strong and solidly grounded power systems, as is the case with most power transmission systems. This presentation will explain the proposed protection algorithm in detail.

The understood and average microprocessor relay life span is on the order of fifteen years. During the course of this life span, there are inherent costs associated with the maintenance of these devices which are generally not considered but are critical to the performance of the device and the intended application. This presentation examines the planned costs associated with such things as NERC testing requirements and manufacturer or customer specific non-critical firmware enhancements.

This session discusses different architectures and the benefits of process bus solutions based on open standards, results and field experiences involving the NCIT, combined with the flexibility and modularity of the stand-alone merging units for process bus IO system. As well, the paper will cover security architectures to ensure highest availability of IEC 61850-9-2 solutions.
