IEEE P1031/D2, Mar 2011

IEEE P1031/D2, Mar 2011 is a draft IEEE guide for the functional specification of transmission static var compensators, with a focus on how these power-system devices should be described for engineering use. It is relevant to components, circuits, devices, and systems in power and energy applications, where clear specification supports planning, procurement, and performance review. By framing functional requirements in a consistent way, IEEE P1031/D2, Mar 2011 helps reduce ambiguity in SVC-related projects.

IEEE P1031/D2, Mar 2011 overview

This technical document addresses the functional specification of transmission static var compensators, commonly used in high-voltage power systems to support voltage regulation and reactive power control. IEEE P1031/D2, Mar 2011 is intended to guide how such equipment is defined, described, and evaluated from a system perspective. In practice, that means it can help align design expectations, interface requirements, and performance criteria for transmission applications where stable operating conditions are important.

Typical use cases

IEEE P1031/D2, Mar 2011 may be used when preparing specifications for transmission-network reactive power support, substation equipment packages, or utility studies involving static var compensators. It is also relevant during engineering review of SVC installations connected to grid assets, where voltage control, system compatibility, and functional requirements must be defined clearly. Procurement teams, designers, and consultants may use it to communicate expectations for equipment behavior and integration in power-system projects.

Why this standard matters

For transmission projects, a clear functional specification helps limit misunderstandings between owners, suppliers, and engineers. IEEE P1031/D2, Mar 2011 supports more consistent documentation of required performance, which can improve procurement clarity, design control, and verification activities. In power and energy environments, that consistency may also reduce project risk by making it easier to compare proposals and assess whether an SVC meets the intended operating needs and system constraints.
