Foreword 

IEEE Std 115-1995 incorporates and updates virtually all of the 1983 edition (reaffirmed in 1991), along with IEEE Std 115A-1987.

The first AIEE "Test Code" for Synchronous Machines (#503) was issued in 1945 and formed the basis for the subsequent IEEE Std 115, which was first published in 1965.

The Synchronous Machinery Subcommittee Working Group #12, which produced this present document, was formed in January 1992, and a revised PAR form, dated April 1992, was approved by the Standards Board in June 1992. This approval included a proposal by the Working Group to divide the new document "Test Procedures for Synchronous Machines," into 2 parts, as follows:

- Part I, Acceptance and Performance Testing

- Part II, Test Procedures and Parameter Determination for Dynamic Analysis

 Part I basically includes all of the sections (1-7) of IEEE Std 115-1983, except section 8. These are now designated sections 1-8.

Part II includes section 8 of IEEE Std 115-1983 plus IEEE Std 115A-1987. These are now designated as sections 9 through 12.

A new feature of this revised and expanded standard is the inclusion of several annexes following sections 5, 11, and 12.

The Working Group believes strongly that the new arrangement will be more convenient to use; the now expanded section 8 from the 1991 document includes three new sections. These are:

- Section 9: Applications of machine electrical parameters

- Section 10: Tests for determining parameter values for steady-state conditions

- Section 11: Tests for evaluating transient or subtransient characteristic values

Section 12 deals with all aspects of standstill frequency response testing of synchronous machines, which was derived from IEEE Std 115A-1987.

Scope

This guide contains instructions for conducting the more generally applicable and accepted tests to determine the performance characteristics of synchronous machines. Although the tests described are applicable in general to synchronous generators, synchronous motors (larger than fractional horsepower), synchronous condensers, and synchronous frequency changers, the descriptions make reference primarily to synchronous generators and synchronous motors. The tests described may be applied to motors and generators, as needed, and no attempt is made to partition this guide into clauses applying to motors and clauses applying to generators. It is not intended that this guide shall cover all possible tests, or tests of a research nature, but only those more general methods which may be used to obtain performance data. The schedule of factory and field tests which may be required on new equipment is normally specified by applicable standards or by contract specifications. This guide should not be interpreted as requiring the making of any specific test in a given transaction or implying a guarantee to meet specific performance indices or operating conditions.

The term specified conditions for tests as used in this guide will be considered as rated conditions unless otherwise agreed upon. Rated conditions apply usually to the following quantities listed on the machine nameplate. These include MVA, terminal voltage (or kilovolts), armature current, and power factor.
