Features: Thermal power plants are not only units for electricity production but also major electricity consumers. The large number of fans and pumps in power plants are the primary targets for energy-saving retrofits, offering significant potential for energy conservation. With the implementation of policies such as the separation of power generation and grid operations and the introduction of competitive bidding for electricity supply, power plants have been actively conducting energy-saving retrofits on their major auxiliary equipment. This aims to reduce plant electricity consumption, lower coal consumption for power generation, and minimize greenhouse gas emissions, thereby generating substantial economic and social benefits. Energy-saving retrofits for fans and pumps, particularly those using variable frequency drive (VFD) technology, are the best solution with the most effective energy-saving results. This book primarily discusses the production process requirements, system design, economic analysis, reliability measures, and harmonic interference issues involved in energy-saving retrofits of fans and pumps in power plants using high-voltage variable frequency technology. It is supplemented by numerous engineering application examples. The book is rich in content and detailed in data, serving as a guide and standard for feasibility studies, equipment selection, installation and commissioning, and performance testing of energy-saving retrofit projects for auxiliary equipment in power plants. It is suitable for reference by professional technicians engaged in energy-saving retrofits of fans and pumps, as well as for students and faculty in relevant disciplines at universities and colleges.
