scope:

This guide describes the electrical and control design of water conveyance facilities associated with hydroelectric projects including associated penstocks, valves, and gates. The guide includes guidance to plan and prepare designs; however, it does not include details of installation, operation, or maintenance guidelines and methodologies. This guide is applicable to design of new facilities and rehabilitation or replacement of existing facilities.

Purpose

This guide provides a description of the terminology, as well as the design practices and principles used in modern electrical and control design of water conveyance facilities associated with hydroelectric projects. The practices and principles are not covered by other guides associated with hydroelectric facilities. This guide is for use by practicing engineers and provides guidance for facility owners and operators. The guide does not cover every possible variation that can be encountered, but it provides a working familiarity with the terminology and principles involved.

Use of this guide

This guide is intended for the practicing engineer who has some familiarity with electrical and control system design. This guide provides a control hierarchy capable of standalone operation or interfacing with other systems. This guide provides comprehensive considerations for design, monitoring, control, protection, and operation of water conveyance facilities associated with hydroelectric projects. It provides guidance in electrical and instrumentation work unique to water conveyance systems. It provides guidance for the safe control of water release systems, bypass systems, and failure modes. It provides reliability measures such as redundancy and power source considerations. It introduces the gate and valve types and associated operating mechanisms. This guide covers power and non-power water conduits including penstocks, tunnels, and canals. It does not include hydraulic turbines or their flow control devices (wicket gates, nozzles, etc.).

This guide does not cover:

Cascade river control systems or waterway navigation locks

Gates that are not normally connected to the hoisting mechanism (e.g., maintenance gates, stop logs, or bulkheads)

Features unique to hydroelectric turbine generator units and pumped storage considerations that are treated in IEEE Std 1010™1

Surge tanks and surge towers

Vacuum breakers and air admission valves

Dam monitoring systems (e.g., leakage flow, piezometers, and movement sensors)

Fire detection and protection

Irrigation systems

Cyber security

Pressure release valves (PRV) for conveyance system pressure transient protection are beyond the scope of this document.

Governing regulations

Local, regional, and federal regulations, codes, and laws should be consulted prior to designing/specifying equipment and conveyances. This may include safety, environmental, water permit, license, and heritage considerations.
