Newton Fund - New Configurations of Power Converters for Grid Interconnection Systems

这个牛顿基金项目将是英国诺丁汉大学与智利塔尔卡大学和康塞普西翁大学的合作项目。根据智利政府2012年3月提出的国家能源战略，智利日益增长的技术发展促使人们寻求能源效率，并将可再生能源和其他发电系统渗透到电力供应网络中。在这种背景下，功率变流器在电能管理中扮演着重要的角色，提供了发电和配电系统之间的互联。该项目将在这样一个集成的电力互联系统中研究新的多模块电力转换架构。这样的架构允许不同类型的发电和负载的电网互联，从而为智利实现了具有成本效益、清洁和可持续的输电和配电结构(这也可以扩展到南美其他地区，甚至欧洲)，并提高了电能质量。该提案的具体目标是采用小巧轻便的多模块电力变流器结构，以实现电网嵌入式发电机。在多参数系统中，需要发展先进的调制和控制算法来调节。所需的控制算法将基于对建议的嵌入式体系结构及其在不同电网条件下的行为的研究，例如低电压、高谐波含量、电压失真和频率变化。建议的转换器架构的功能将通过硬件验证和测试进行验证。这样的智能电力系统应该清楚地解决安全、经济高效的能源的两个最重要的因素：提高效率和维持供应。

This Newton Fund project will be a colaboration between the University of Nottingham, Uk and the Universities of Talca and Concepcion, Chile. According the National Energy Strategy proposed by the Chilean Government in March 2012, the growing technological development in Chile has lead to the search of energy efficiency and the penetration of renewable energies and other generation systems to the electricity supply network. In this context, power converters play an important role for the management of electric energy, providing the interconnection between the generation and the distribution systems. This project will investigate new multi-modular power conversion architectures within such an integrated power interconnection system. Such architectures allow the grid interconnection of different types of generation and loads enabling a cost effective, clean and sustainable electrical transmission and distribution structure for Chile (which could also be extensible to the rest of South-America and even Europe) with improved power quality. Specific objectives of the proposal are small and lightweight multi-modular power converter structures to enable grid embedded generators. The development of advanced modulation and control algorithms are needed for conditioning in multi-parameter systems. The required control algorithms will be based on a study of the proposed embedded architectures and their behavior for different grid conditions such as low voltage, high harmonic content, voltage distortion, and frequency variations. Functionality of proposed converter architectures will be verified through hardware validation and testing. A smart electrical system as such should clearly address the two most important factors for secure, cost-effective energy: improving efficiency and maintaining supply.
