Chapter 16

Hydroelectric Dam and Tidal Gates

Abstract

This example provides a Safety Integrity Level (SIL) assessment of the proposed flood gate control system (FGCS) at a hydro-electric dam, demonstrating that it meets the identified hardware reliability and minimum configuration requirements in accordance with IEC 61508. In order to identify the SIL requirements, a Layer of Protection Analysis (LOPA) was conducted at a meeting of interested parties. The study considered the hydro-electric plant to determine potential risks associated with the specified hazards.
