IEEE 1020-2011 is a technical guide for controlling small hydroelectric power plants rated from 100 kVA to 5 MVA, presented as a redline edition for easier review of changes. It focuses on control considerations for plant operation, helping engineers and operators understand how to manage generation equipment, supervision, and related electrical systems in a compact hydro setting. As a reference standard, it supports more consistent design and evaluation of these installations.

About IEEE 1020-2011

This document provides guidance for the control of small hydroelectric power plants, with attention to the operating needs of systems in the 100 kVA to 5 MVA range. IEEE 1020-2011 is relevant where plant control must coordinate generation, monitoring, and protective functions within a limited-scale hydro facility. The redline format is useful for identifying revisions against earlier text, making it easier to track technical changes during specification review, maintenance planning, or engineering comparison work.

Where is IEEE 1020-2011 used?

IEEE 1020-2011 is typically used in small hydroelectric stations, utility-connected renewable generation projects, and engineering work involving plant control systems for low- to mid-size hydro units. It can support design and review activities for governors, supervisory controls, sensing devices, and electrical interfaces tied to plant operation. The standard is also useful in procurement and documentation workflows when specifying control-related requirements for compact hydro installations.

Importance in practice

In practice, this guide helps reduce uncertainty when planning or evaluating control arrangements for small hydro plants. IEEE 1020-2011 supports more consistent engineering decisions by giving a common reference for control-related expectations, which can improve coordination between design, operations, and maintenance teams. It may also help with compliance discussions, equipment selection, and testing preparation by clarifying how control functions should be approached for reliable plant performance and lower operational risk.
