Title
Rules for Steam Turbine Thermal Acceptance Tests - Part 3: Thermal Performance Verification Tests of Retrofitted Steam Turbines
Regles Pour Les Essais Thermiques De Reception Des Turbines A Vapeur - Partie 3: Essais De Verification Des Performances Des Turbines A Vapeur Renovees
International Electrotechnical Commission
Publication Date:

Scope:
This part of IEC 60953, also called "retrofit code" (RC), establishes a supplementary retrofit code for thermal verification tests of retrofitted steam turbines.
The rules given in this standard follow the guidance given in IEC 60953-2, hereinafter called the RS but contain amendments and supplements regarding guarantees and verification of the guarantees by thermal acceptance tests on retrofitted steam turbines.
General principles for the preparation, performance, evaluation, comparison with guaranteed values and the determination of the measurement uncertainties of verification tests are given in this standard.
This standard is applicable only when the retrofit involves some hardware change in the steam turbine equipment. Conversely, any modification on the cycle or any retrofit of other equipment of the power plant (e.g. boiler, feedwater heaters, etc.) is not covered by this standard.
Object
The purpose of this standard is to establish appropriate guaranteed parameters, to verify these guarantees and to determine measurement uncertainty.
The guarantees with their provisions should be formulated completely and without contradiction (see 2.4 and 2.5 of IEC 60953-2). The verification tests may also include such measurements as are necessary for corrections according to the conditions of the guarantee and checking of the results.
