本文的目的是分析和量化采用不同风力涡轮机技术（特别是定速、转子电阻控制的变滑差和矢量控制的变速技术）的风力发电厂的惯量和频率响应。本文将介绍风力涡轮机在频率下降期间对惯性和主频率响应做出贡献所需的基本理论、工作范围和修改。我们将演示允许变滑差和变速风力涡轮机为主机电力系统电网贡献惯性的实用方法。这些方法基于在扭矩控制环路中包含频率误差和频率信号的变化率，以及风速低于和高于其额定值时的桨距控制动作。将在时域中进行详细的仿真模型以证明这些方法的有效性。
The objective of this paper is to analyze and quantify the inertia and frequency responses of wind power plants with different wind turbine technologies (particularly those of fixed speed, variable slip with rotor-resistance controls, and variable speed with vector controls). The fundamental theory, the operating range, and the modifications needed for the wind turbine to contribute to the inertial and primary frequency response during the frequency drop will be presented in this paper. We will demonstrate practical approaches to allow variable slip and speed wind turbines to contribute inertia to the host power system grid. The approaches are based on the inclusion of frequency error and the rate of change of frequency signals in the torque control loop and pitch control actions for wind speeds below and above its rated value. Detailed simulation models in the time domain will be conducted to demonstrate the efficacy of the approaches.
