Smart city has become an important direction of urban development. Focusing on the construction of smart city, it can reflect the ideal practical effect in many aspects, effectively improve the level of urban development and operation, and also show better in urban planning. Strong influence requires urban planning for adaptive adjustment. This paper from the core of a small wind power system is the grid-connected inverter. According to the main topology of small wind power generation inverter and grid-connected system, a systematic modeling of small wind power generation system is built. In order to make up for the deficiency of the traditional control strategy for small wind power grid-connected inverter, this paper puts forward a fuzzy control and quasi-PR control method to be applied to the synchronization control of grid-connected inverter. The simulation experiment is conducted by using MATLAB/SIMULINK platform, and the test is conducted by means of combining self-designed system hardware circuit, and the results show that compared with the PR method, the grid current synchronization error can be reduced to smaller, adaptability, and anti-disturbance can be greatly improved through the proposed method and, consequently, has a better application value for small wind power grid-connected inverter.

智慧城市已经成为城市发展的重要方向。着眼于智慧城市的建设，它可以在许多方面反映理想的实际效果，有效地提高城市的发展和运营水平，在城市规划中也表现得更好。强大的影响力要求对城市规划进行适应性调整。本文从小型风力发电系统的核心是并网逆变器。根据小型风力发电逆变器和并网系统的主要拓扑结构，建立了小型风力发电系统的系统模型。为了弥补传统的小型风电并网逆变器控制策略的不足，提出了一种模糊控制和准PR控制方法，用于并网逆变器的同步控制。
