Abstract

While major faults in grid-connected PV systems are easily detectable using currently available methods, there are some instances where fault conditions can escape normal detection means. This paper proposes a nonlinear observer to detect these smaller faults using a model-based approach. This observer is validated through a Lyapunov stability analysis and verified by simulation results. The proposed observer is simple to calculate and can be utilized by a system expert to detect the presence of a fault condition.
一种光伏应用的非线性故障检测方案
虽然目前可用的方法很容易检测到并网光伏系统中的重大故障,但在某些情况下,故障情况可能无法通过常规检测手段进行检测。本文提出了一种基于模型的非线性观测器来检测这些较小的故障。该观测器通过李雅普诺夫稳定性分析和仿真结果进行了验证。所提出的观测器计算简单,可以被系统专家用来检测故障条件的存在。
