摘要

本文介绍了在2008年的四个主要事件中加拉加斯电频率的行为分析。频率由故障记录仪的电压信号计算得到。4月29日和9月1日的事件是国家电网输电线路故障，10月19日的事件是765kV (Guri-Malena)两条主线路的不稳定跳闸。在这些事件中，频率演变导致加拉加斯电力公司(EDC)的孤岛计划失败，但后来EDC崩溃。十二月十一日的事件是电力中心的离岛计划运作不稳定，而低频率的减载避免了电力中心的全面崩溃。对这些事件的分析有助于提出相应的建议。

Analysis of the electrical frequency in Caracas during four major events of the year 2008

This article presents an analysis of the behavior of the electrical frequency in Caracas during four major events of the year 2008. The frequency was computed from the voltage signals of the fault recorders. The events of April 29 and September 01 were faults in transmission lines of the National Grid, and the event of October 19 was the erratic trip of two main lines at 765kV (Guri-Malena). In these events, the frequency evolution caused the trip of the islanding scheme of the Caracas' electric utility (EDC), but later EDC collapsed. The event of December 11 was the erratic operation of the islanding scheme of EDC, and the underfrequency load shedding avoided a total collapse of EDC. The analysis of these events has been useful to do the corresponding recommendations.
