Abstract

This paper analyzes the electrical parameters of areas that contain distributed generation facilities. It demonstrates the necessity of stricter requirements to the performance of energy system automated systems, especially in island operation. It is noted that implementing a special procedure for truncating the standard sequential analysis (Wald analysis) for automated decision-making is a time-consuming process. By ensuring the constancy of first- and second-kind errors at each step of the Wald analysis, one can generate adaptable settings. The paper uses evidence from an automated underfrequency load shedding unit to show that a modified sequential analysis algorithm performs twice as fast. The authors present guidelines on how to adopt this modified algorithm in existing or newly developed energy system automated systems.

分布式发电区域电网自动化系统中的高性能顺序分析

摘要

本文分析了包含分布式发电设施的区域的电气参数。它说明了对能源系统自动化系统的性能提出更严格要求的必要性，尤其是在孤岛运行中。请注意，实施特殊程序以截断标准顺序分析（Wald分析）以进行自动决策是一个耗时的过程。通过在Wald分析的每个步骤中确保第一类错误和第二类错误的恒定性，可以生成适应性设置。本文使用来自自动低频减载单元的证据来表明，改进的顺序分析算法的执行速度是后者的两倍。作者提出了有关如何在现有或新开发的能源系统自动化系统中采用这种修改算法的指南。
