Force commutated high power electronics

导语：每个人都熟悉电子产品，因为他们熟悉通信(电视、广播、互联网、无线和移动)和消费产品。但这类电子产品仅限于低功率范围。电力电子处理的是兆瓦级的电力公用事业。例如，出于安全原因，水电-魁北克通过直流线路连接到美国新不伦瑞克(不久的将来还将连接到安大略水电)。交-直-交转换设备是基于电力电子技术的。所有可再生能源技术(风能、光伏、太阳能等)需要类似的设备从变频(直流到60赫兹交流，或变频交流到60赫兹交流)。 经过几十年的研究，“强制换向高功率电子学”旨在改进高压直流(HVDC)站和灵活交流输电系统(FACTS)控制器形式的电力电子换流器，下一阶段包括集成可再生能源的变频器，以提高电网的整体动态性能。令人振奋的前景是：当可再生能源的普及率达到30%时，电网中的电力电子可控功率(来自变频器)也将达到30%。 目的：除了继续改进高压直流输电和FACTS设备外，增加的挑战是使用30%的电力电子控制来稳定和改善大型互联电力系统的阻尼，这些系统的区域间振荡过去曾导致停电。 科学方法： 除了电力电子技术外，研究方法还将扩展到小干扰稳定性分析、特征函数概念的应用和超级计算机并行处理机的特征函数计算。

Introduction: Everyone is familiar with electronics because of communication (TV, radio, internet, wireless and mobile) and consumer products. But such electronics are limited to low power ranges. Power electronics deal with the mega-watt levels of electric utilities. Hydro-Quebec, for example, is connected to New Brunswick, USA (and Ontario Hydro in the near future) by dc lines for reasons of security. The equipment for converting from AC to DC and back to AC are based on power electronic technology. All renewable energy technologies (wind, photovoltaic, solar, etc. ) require similar equipment from frequency changing (DC to 60 Hz AC, or variable frequency AC to 60 Hz AC). After decades of researching under the theme, "Force commutated high power electronics" to improve power electronic converters in the forms of High Voltage DC (HVDC) stations, and Flexible AC Transmission Systems (FACTS) controllers, the next phase of consists of integrating the frequency changers of renewable energy sources to improve the overall dynamic performance of power grids. The exciting prospect is: when renewable energy sources reach penetration of 30%, the power electronically controllable power (coming from the frequency changers) in the power grid becomes 30% also. Objective: Besides continuing to improve HVDC and FACTS equipment, the added challenge is to use the 30% power electronically control to stabilize and improve the damping of large interconnected power systems whose inter-area oscillations have, in the past, led to blackouts. Scientific Approach: Besides power electronic technologies, the research methods will be extended to small signal stability analysis, application of eigenfunction concepts and computation of eigenfunctions by parallel processors of supercomputers.
