风电变流器控制技术在电力系统中的应用研究
摘 要
本论文对风电变流器控制技术在电力系统应用中的问题进行了综合分析和研究，并提出了多种改进措施。研究结果表明，当前风能发电系统的功率因数较小、电压波动和抗扰性差等问题，会对电力设备和电网带来一些负面影响。为了解决这些问题，我们提出了模糊PID控制算法、谐波抑制技术、模型预测控制策略以及神经网络控制技术等多种改进措施。这些方法能够有效地提高风能发电系统的控制精度、稳定性和可靠性，进一步推动清洁能源在电力系统中的广泛应用和普及。

Abstract
In this paper, the application of wind power converter control technology in power system is analyzed and studied comprehensively, and a variety of improvement measures are put forward. The results show that the current wind power generation system has low power factor, voltage fluctuation and poor immunity, which will bring some negative effects on power equipment and grid. In order to solve these problems, we put forward a variety of improvement measures, such as fuzzy PID control algorithm, harmonic suppression technology, model predictive control strategy and neural network control technology. These methods can effectively improve the control precision, stability and reliability of wind power generation system, and further promote the wide application and popularization of clean energy in power system.
