Book Description
An in-depth exploration of shipboard power generation and distribution system design that utilizes variable frequency drives The variable frequency drive (VFD) application is a proven technology for shore-based applications. However, shore-based VFDs often are unsuitable for shipboard applications because the power generation and distribution fundamentals are completely different. VFD Challenges for Shipboard Electrical Power System Design explores the problems presented by variable frequency drives as they are applied in shipboard power generation and distribution system design and offers solutions for meeting these challenges. VFDs with configurations such as six pulse drive, 12 pulse drive, 18 pulse drive, active front end, pulse width modulation and many others generate many different levels of harmonics. These harmonics are often much higher than the regulations allow. This book covers a range of techniques used to provide ships with efficient energy that minimizes mechanical and electrical stress. This important book: Offers a comparison of shipboard grounding and VFD grounding Contains an analysis of the VFD effect in terms of shipboard power quality Includes specific examples of Department of Transportation standards regarding VFDs Written for commercial and naval engineers designing ships and/or shipboard power systems, VFD Challenges for Shipboard Electrical Power System Design is a comprehensive resource that addresses the problems and solutions associated with shipboard applications of VFD.

Book Description
With the increasing application of power electronics to shipboard electric power systems, there is a need for studying power systems in an object- oriented, graphical environment in order to examine the interrelations of the various system components. This thesis presents a method of analyzing shipboard electric power systems in a graphical environment. The simulation method used allows for real-time observation of the various power system measurements of interest. The machine equations, including those for voltage, torque, and rotor angle are developed which permit analyzing the machine in any chosen reference frame depending on the study being undertaken. Regulars for both speed and field voltage are developed and the stability of the speed regulator is examined. A means of modeling a load for a synchronous generator is then shown which accurately interrelates the loading of the generator and the frequency and voltage output of the machine. This load is then connected to the synchronous generator and two different scenarios are examined including a fifty percent load change and a fault study. Graphs showing the output of these studies are presented. Electric power systems, Electric machine simulation, Shipboard power systems, Power system modelling.

Book Description
Analysis was performed to quantify and compare the reliability of several different notional shipboard DC distribution system topologies in serving their equipment loads. Further, the relationship between the relative placement of loads and generators within a distribution system and the system's reliability was investigated, resulting in an algorithmically-derived optimal placement configuration in the system topology found to be the most reliable in the initial analysis. Using Markov models and fault-tree analysis, system reliability indices were derived from distribution system component reliability indices, and these values were compared between competing topologies and equipment configurations. A distribution system based on the breaker-and-a-half topology often used in terrestrial utility substations was found to be superior in terms of reliability to the currently-standard ring bus topology. Expected rates of service interruptions to equipment systems served by the breaker-and-a-half system were reduced overall, in some cases dropping dramatically to less than one expected interruption per 10,000 years. This improvement, however, came at the expense of requiring more circuit breakers in the distribution system's construction. Within this breaker-and-a-half distribution system, an optimal placement of loads and generators was algorithmically derived, which further improved the reliability of the system. This improvement over the base case was marginal, but the optimized placement configuration was able to reduce the expected interruption rate of the ship's radar system by over 40%.

Book Description
Power distribution and quality remain the key challenges facing the electric utilities industry. Choosing the right equipment and architecture for a given application means the difference between success and failure. Comprising chapters carefully selected from the best-selling Electric Power Distribution Handbook, Electric Power Distribution Equipment and Systems provides an economical, sharply focused reference on the technologies and infrastructures that enable reliable, efficient distribution of power, from traversing vast distances to local power delivery. The book works inward from broad coverage of overall power systems all the way down to specific equipment application. It begins by laying a foundation in the fundamentals of distribution systems, explaining configurations, substations, loads, and differences between European and US systems. It also includes a look at the development of the field as well as future problems and challenges to overcome. Building on this groundwork, the author elaborates on both overhead and underground distribution networks, including the underlying concepts and practical issues associated with each. Probing deeper into the system, individual chapters explore transformers, voltage regulation, and capacitor application in detail, from basic principles to operational considerations. With clear explanations and detailed information, Electric Power Distribution Equipment and Systems gathers critical concepts, technologies, and applications into a single source that is ideally suited for immediate implementation.

Book Description
Shipboard electrical distribution systems are changing significantly with the introduction of solid state frequency converters, introduction of electric propulsion and integrated electric drive, and the possibility in the future of large combat systems pulsed loads. Existing computer tools for analyzing power systems have difficulty simulating these changing conditions. To assist in the evaluation and analysis of future shipboard electrical distribution systems, the Shipboard Electrical Plant Simulation Program (SEPSIP) was developed. The key feature of SEPSIP is its use of implicitly defined input variables and implicit variables which allow for every element of the simulation to be mathematically isolated from every other element. When the constitutive laws of an element are satisfied an appropriate set of input variables, all of the implicit variables have zero value. The network description generates the input variables based on the network topology and the results of a Newton Raphson iterative scheme. The key advantage to this method is that the network description of a node closely models an actual electrical node. To demonstrate the abilities of SEPSIP, several simulations involving synchronous generators, induction motors, and voltage regulator dynamics were conducted. In all simulations, SEPSIP provided results that matched data generated by other simulation methods.
