摘要
从国网公司加快建设统一坚强智能电网重点工作出发，针对目前电网智能化过程中，配电网电能质量改善装置——配电系统静止无功补偿器（DSTATCOM）存在的控制器精确度低、控制效果不理想等问题，分析研究了DSTATCOM在a—b—c坐标下与d—q-0坐标下的数学模型，并采用输入输出反馈线性化控制策略使系统实现了输入输出状态的精确线性化。从而将复杂的非线性系统综合问题转化为线性系统的综合问题。
For the State Grid Corporation is focused on speeding up to build unified and strong smart grid, there have some problems, such as a low accuracy and a unsatisfactory result in controller, in the distribution power quality improvement device -distribution static compensators （abbreviated as DSTATCOM）, during intelligent process for the existing power grid. In this article, the mathematical model of DSTATCOM in the a - b - c coordinates and the d - q - 0 coordinates have been analysed. Then the system achieved the status of input and output exact linearization, by use of input - output feedback linearization control strategy. Thus, the synthesis problem of complex nonlinear system is transformed into a linear system synthesis issue.
