ABSTRACT / САЖЕТАК:
The new unit B3 at the Kostolac Thermal Power Plant began operation in September 2024 after a trial period. The new unit has supercritical live steam parameters of 242 bar and 566 oC and a gross power of 350 MW. The equipment manufacturer provided guarantees for the value of gross power, gross and net unit efficiency and share of the unit’s own consumption. Acceptance tests were conducted by the Laboratory of Thermal Turbomachinery – Faculty of Mechanical Engineering in Belgrade according to the ASME PTC 46 standard in October 2024. The paper presents the requirements of the standard for testing the new unit, as well as the approach to determining the share of own consumption and correction of test results. For comparing measured values with guaranteed values, measurement uncertainty is taken into account, and the paper will present the procedure for determining measurement uncertainty.
