摘要

本文介绍了一种用于澳大利亚孤岛液化天然气设施的汽轮机负荷分担和减载系统。该系统包括三种独立且冗余的减载方案:基于过程的偶然性减载方案、基于预定义负载组和负载对的高速低频减载方案和基于系统频率监督的渐进式过载减载方案。除了减载方案外，该站点还包括一个具有频率控制、电压控制、自动同步和涡轮负荷共享方案的发电控制系统。断路器半配置使快速减载方案复杂化。硬件在环测试的结果是共享的。

Case Study: Turbine Load-Sharing and Load-Shedding System Foran Australian LNG Facility

This paper presents a turbine load-sharing and load-shedding system for an islanded liquefied natural gas facility in Australia. The system includes three independent and redundant load-shedding schemes: process-based contingency load shedding with predefined load group and load pairs, high-speed underfrequency-based load shedding, and progressive overload shedding with system frequency supervision. In addition to the load-shedding schemes, the site includes a generation control system with frequency control, voltage control, automatic synchronization, and turbine load-sharing schemes. A breaker-and-a-half configuration complicates the fast load-shedding scheme. Results from hardware-in-the-loop testing are shared.
