Description / Abstract:
This document is a guide for field testing and commissioning of
static var compensators (SVCs). As such, the document establishes
general guidelines and criteria for field testing to verify the
specified performance of SVC systems. Many clauses will be useful
for compensator systems using gate turn-off (GTO) thyristor
technology (static compensator [STATCOM]) or other semiconductor
devices such as insulated gate commutated transistor (IGCT).
This guide does not
a) Cover factory and simulator tests of SVC system components
(but it assumes that such tests have been performed
beforehand).
b) Discuss the division of responsibility between user and
supplier, since this division is usually defined in the contract
between buyer and supplier. Most often, however, the practice is
for the equipment, subsystem, and commissioning tests to be
performed by the supplier, and the acceptance tests to be performed
by the buyer or user.
Purpose
The purpose of this guide is to help users of SVCs carry out a
field test program prior to placing an SVC into service. The major
elements of a commissioning program are identified so that users
can formulate a specific plan that is suited to their own SVC. Such
a test program should cover the following:
a) Equipment tests within the SVC system
b) Tests of the various subsystems that comprise the SVC
system
c) Commissioning tests for the complete SVC system
d) Acceptance testing of the complete SVC system
It should be recognized that there are many ways in which a
particular SVC may be commissioned, and also that it is not the
purpose of this guide to endorse a specific procedure to the
exclusion of other methods.
Depending on the purpose of the SVC design (transmission type or
smaller size used for other purposes) some tests may not be
required. In particular, some control system tests may be included
in the factory tests. Also, acceptance tests may be integrated into
any of the categories listed above.
