摘要

虚拟同步发电机（virtual synchronous generator，VSG）技术可以模拟同步发电机的特性，具有惯性、阻尼、调频调压等优点，能够提升系统频率的稳定性。当电网频率出现波动时，在风电并网逆变器的控制中引入VSG控制技术可用于支撑电网频率。由于固定惯量阻尼的VSG控制暂态超调较大，频率易超出频率波动阈值。针对此问题，通过建立VSG的小信号模型，分析了转动惯量及阻尼系数对频率稳定性的影响，并提出了一种考虑阻尼比的转动惯量阻尼综合自适应控制方案，在电网频率波动情况下，改善了系统的暂态性能，进一步提升了频率的稳定性。仿真对比结果表明，所提控制策略与传统固定惯量阻尼的VSG控制及转动惯量阻尼交错自适应VSG控制相比具有优越性。

Abstract

Virtual Synchronous Generator(VSG)technology can simulate the characteristics of synchronous generator

offering such advantages as inertia

damping

frequency and voltage regulation

thereby improving the stability of the system frequency. In case of grid frequency fluctuation

the introduction of VSG control technology into the control of wind power grid connected inverter can support the grid frequency. Due to the large transient overshoot associated with VSG control under fixed inertia damping

the frequency is prone to exceeding the frequency fluctuation threshold. To address this issue

a small signal model of VSG is established to analyze the influence of moment of inertia and damping coefficient on frequency stability.Furthermore.

an integrated adaptive control scheme for inertia and damping that accounts for the damping ratio is proposed

which improves the transient performance of the system and further enhances frequency stability under grid frequency fluctuations. The comparative simulation results show that the proposed control strategy exhibits advantages over both conventional VSG control with fixed inertia damping and the VSG control with stagged adaptive inertia and damping.
