Conventional and recommended arc power and energy calculations and arc damage assessment

The costs associated with fires initiated by arcing faults depend on the extent of the damage. In some cases, costs have exceeded $100 000 000. The personal losses associated with a serious injury or fatality are incalculable. When an arcing fault occurs, qualified in-house personnel and/or professional consultants try to determine the factors involved in the fault's initiation. Investigators also serve as expert witnesses in any pending lawsuits related to the accident. In fact, the growing interest in accident investigation has led to the establishment of an IEEE workgroup in forensics. Even with sophisticated techniques like scanning electron microscopes used to provide magnified photographs of arc damage, only a limited amount of applicable technical information on arcing faults exists for reference. Much of the engineering reference information on calculating arc currents and assessing arc damage is 25-50 years old. Recent papers by the authors discussed calculating arc currents. This paper presents a method to determine the power released by a single-phase-to-ground arc and provides graphs for quick reference. Commonly used methods for calculating arc power and energy and quantifying damage are also discussed. The recommended and conventional methods are used to determine arc energy and to identify the damage threshold in a typical system and the results are compared.     

Present and Future Trends and Needs in Electric Power Quality Sensors and Instrumentation

Sensors and instrumentation systems form an important part of power quality assessment and preservation. In this paper, the present and future trends in power quality instrumentation are discussed and the present capabilities are identified (e.g., bandwidth, dynamic range, quantities measured). Innovative methods of instrumenting nonsinusoidal voltages and currents are described, including applications of the Global Positioning System (GPS), solid state sensors, sensors that involve light and video, advanced data compression techniques, and advanced state estimation. The cost-to-benefit ratio of sensor development is evaluated in the context of the deregulated electric utility business environment.

Tracing active and reactive power between generators and loadsusing real and imaginary currents

In a competitive environment, usage allocation questions must be answered clearly and unequivocally. To help answer such questions, this paper proposes a method for determining how much of the active and reactive power output of each generator is contributed by each load. This method takes as its starting point a solved power flow solution. All power injections are translated into real and imaginary currents to avoid the problems arising from the nonlinear coupling between active and reactive power flows caused by losses. The method then traces these currents to determine how much current each source supplies to each sink. These current contributions can then be translated into contributions to the active and reactive power output of the generators. It is also shown that the global contribution of a load can be decomposed into contributions from its active and reactive parts. This decomposition is reasonably accurate for the reactive power generation. To determine the contributions to active power generation, the previously-described method based on the active power flows is recommended     

Generator protection and CT-saturation problems and solutions

This paper presents a new generator relay design, stator differential function in particular, coping with extreme cases of current transformer (CT) saturation: both ac saturation under large currents and/or residual flux; and dc saturation under low currents but large and long-lasting dc components. The algorithm is a subcycle algorithm with fastest times reaching half a cycle including overall response of the relay hardware. Analysis of the response of a traditional differential function under CT saturation is included to provide setting guidelines for legacy relays.
