城市轨道交通起停频繁、速度变化快、制动能量大,可以重新利用制动能量的再生制动技术也在不断改进。回顾了各类常规制动技术及其特点,并介绍了最新的能馈式再生制动技术,研究论述能馈式再生制动技术对电网的影响,从电能质量、电能计量、继电保护三个方面分别进行分析,有助于电网应对城市轨道交通再生制动电能的注入。
Starting and stop of urban rail transit frequently, rapid changes in speed, braking energy, braking energy can re-use of regenerative braking technology is also constantly improving. Various types of conventional braking technology and its characteristics are reviewed. The latest regenerative braking technology with feed-in regenerative braking is introduced. The influence of regenerative braking technology on the power grid is discussed. From the aspects of power quality, energy metering, relay protection The analysis of each aspect will help the power grid to deal with the injection of regenerative braking energy in urban rail transit.
