3124: New York State Power Grid Geomagnetic Storm and E3-HEMP Threat - Vulnerability Assessments

This study provides a detailed review of the NY State power grid to assess the vulnerability of the grid to probable and extreme geomagnetic storm events and similar electromagnetic disturbances triggered by a high-altitude nuclear burst generating a geographically widespread disturbance in the geomagnetic field (i.e. Late-time EMP or E3 environment). This study undertook the development of detailed system models of the backbone of the US transmission grid and more detailed representation

30145: Simulation Study of Safe Grounding Methods for the Operation of High Voltage Disconnect Switches

High-voltage (HV) disconnect switches are typically operated without incidence; however, each operation presents an increased risk for flashover. When a flashover occurs, the worker operating the switch can experience a potentially hazardous voltage (exposure voltage) across their body. Despite extensive discussions in the industry, the best switch grounding method to limit the exposure voltage experienced by the operator has yet to be established.This report on safe grounding methods, covering

3001: Accelerated Aging Test for Elastomer-Based Gasket Materials

The majority of large electrical equipment is oil-filled. The oil serves as both coolant and the primary electrical insulating medium. Typically, this equipment is in welded steel housings, with openings for access, connections, etc. Soft gaskets are installed around all of these openings, to prevent leakage. Good gasket materials will maintain an oil-tight seal for the life of the equipment, or at least until disassembly is eventually needed.Too often, the materials chosen fail during in-servic

50133: System-wide Reliability Forecast Model

The primary objectives of this project were to identify best practices in reliability forecasting via research and surveying, and through the survey to identify current-state reliability practices and develop a tool that will help utilities derive their forecasts. The tool developed as part of this initiative was intended to use best practices in reliability forecasting to provide both utilities and regulators with an accurate understanding of system performance.Industry research in the form of

3718: Ensuring the integrity of Working Ground Connection Points in Stations

Temporary protective grounding is crucially important for ensuring the safety of workers, the public and the protection of power system equipment. The proper connection of working grounds to the buried ground grid conductors is essential to safe working conditions in a substation. This report summarizes the key findings of technical standards and reports, as well industrial experiences on temporary protective grounding, compatibility between attachment points and clamps, and worker exposure volt

3511: Electric Utility Guideline for Asset Management of Physical Security Assets

Utilities typically employ asset management programs and systems to manage the lifecycle of field equipment such as poles, insulators, transformers, turbines, and generator components. Due to increased physical and cyber security threats to these traditional utility assets, and due to regulatory requirements, such as the North American Electric Reliability Corporation Critical Infrastructure Protection (NERC CIP), utilities have been deploying and managing increasing numbers of security assets.

3502: Assessing Transmission Station Security Threats and Risks

The process for assessing threats and risks to transmission stations is applicable in any environment where people and/or assets may be at risk from a security-related incident or event that could result in human death, injury, or loss of an asset.The goal of this project is to provide utilities with a template that may be used in its entirety or in part to conduct Threat Risk Assessments (TRA) on sites of varying size and complexity.Zone managers, familiar with issues associated with safety and

0395: Hydraulic Generating Station Equipment Maintenance Planning and Scheduling Guide

CEATI participants operate and maintain over 1,000 generating stations located throughout North America, Europe, and Oceania. The maintenance work conducted at these stations is widely recognized as an essential business process for achieving strategic goals of safety, reliability, and production in a cost-effective manner. However, too often, the attainment of these goals is not supported by effective maintenance planning and scheduling.The purpose of the Maintenance Planning and Scheduling gui

3131: PMUs: New Applications and Disturbance Monitoring

With over 1,700 PMUs (Phasor Measurements Units) deployed in the North American grid, numerous PMU-based applications are being developed by vendors, utilities, and academia. These applications have various functionalities and different technology readiness levels, and fall into different categories based on their functionalities and time horizon of use.During this project, the author worked closely with NASPI, DOE, NERC SMS (Synchronized Measurement Subcommittee), IEEE PES CFWG (Cascading Failu

0129: Utilization of Fossil Plant CO2 for the Production of Syngas for Synthetic Fuels and Chemicals

This document summarizes the work performed by SAS to study the utilization of heat as hightemperature steam and CO2 from a fossil fuel power plant. The study also focused on the use ofelectricity from the grid to produce syngas using high-temperature co-electrolysis (HTCE)technology. This technology uses solid oxide electrolysis cells (SOECs) operating at hightemperatures. The study included a literature review of the latest developments in HTCE, selectionof a baseline power plant and developme
