Full title and description

IEEE Std 1031-2011 — Guide for the Functional Specification of Transmission Static Var Compensators. This guide documents an approach to preparing a functional specification for transmission Static Var Compensators (SVCs), intended as a base specification with informative material to help users modify or develop clauses for specific applications.

Abstract

Provides guidance and a template-style approach for defining the functional and performance requirements, control and protection functions, interface requirements, and testing/commissioning criteria for transmission SVC installations using conventional thyristor technology. The guide is applicable in many cases to other semiconductor-based compensators (for example STATCOMs), but excludes SVCs primarily associated with DC converters or those intended for load-disturbance or phase-unbalance correction.

Scope

The standard guides the preparation of a functional specification for transmission Static Var Compensators (SVCs) using conventional thyristor technology. It focuses on functional and performance requirements, control, protection, interfaces, and testing/commissioning criteria for transmission-class SVCs. It is not intended to cover SVCs that are primarily associated with HVDC converters or devices designed primarily for correcting load disturbances or phase unbalance, though many sections are transferable to STATCOMs and other semiconductor-based compensators. General commercial terms and contract conditions are outside the scope.

Key topics and requirements

• Specification structure and recommended clauses for a functional specification (template-style guidance).
• Functional and performance requirements (voltage/reactive power capability, response times, stability considerations).
• Control system functions and modes (voltage control, reactive power control, coordination with system controls).
• Protection and monitoring requirements (fault response, alarms, trips, telemetry).
• Interface and communications requirements (electrical, control, supervisory interfaces).
• Testing, commissioning, and acceptance criteria—including field tests and functional verification.
• Informative annex material to help adapt base clauses for specific project needs.

Typical use and users

Used by transmission utilities, substation and system planning engineers, protection and control engineers, equipment OEMs, consulting engineers, procurement/specification teams, and project managers when preparing or reviewing functional specifications for transmission SVC installations or when evaluating vendor proposals and commissioning plans.

Related standards

Closely related IEEE documents include the earlier IEEE Std 1031-2000 (the prior edition) and IEEE guides on SVC field testing (for example IEEE Std 1303 series). Other IEEE/PES and industry standards on protection, substation equipment, and testing practices are commonly referenced in conjunction with this guide.
