摘要
从国家电网公司加快建设坚强智能电网重点工作出发,针对目前配电网电能质量改善装置——配电系统静止无功补偿器(DSTATCOM)存在控制器精度低、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。
The key work for State Grid is to speed up building strong smart grid. In the light of some problems existed in the distribution static compensators （DSTATCOM） for improving power quality, such as a low accuracy and a unsatisfactory result in controller, the analysis and study of the mathematical model of DSTATCOM in the a-b-c coordinates and the d-q-0 coordinates was carried out. 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＇s synthesis problem.
