摘要

本文第一部分揭示了电网成形（GFM）逆变器现有故障电流限制（FCL）方法的各种缺点。本文第二部分开发了一种新的 FCL 方法，克服了这些缺点。此外，本文提出的 FCL 方法遵循了最新电网规范对基于逆变器的资源 (IBR) 低电压穿越模式的严格要求。这使得 GFM 逆变器在故障期间的精确响应完全可预测。这种可预测性是可靠设计/设置保护系统、运行和规划 IBR 渗透率高的电网的先决条件。本文使用 PSCAD 仿真来证实所提出的方法是否符合这些目标。论文还利用仿真结果将这种新方法与现有的 GFM 逆变器 FCL 解决方案进行了比较。

Fault Current Limiting and Grid Code Compliance for Grid-Forming Inverters — Part II: Solution

Part I of this paper unveiled various shortcomings of existing fault current limiting (FCL) methods for grid-forming (GFM) inverters. Part II of this paper develops a new FCL method that overcomes these drawbacks. Additionally, the FCL method proposed in this paper follows the strict requirements of recent grid codes for the low-voltage ride-through mode of inverter-based resources (IBRs). This makes the exact response of GFM inverters during faults fully predictable. Such predictability is a prerequisite for the reliable design/setting of protection systems, operation, and planning of power grids with high penetration of IBRs. The paper uses PSCAD simulations to corroborate if the proposed method meets these objectives. It also uses simulation results to compare this new method with existing FCL solutions for GFM inverters.
