Renewal of machine transformers Ud1 and Uk1

This tender concerns the renewal of two machine transformers, identified as Ud1 and Uk1, for the planned recommissioning of the Hamburg-Harburg converter station. The converter station utilizes frequency-elastic grid coupling converters, which are primarily composed of two rigidly coupled rotating electrical machines: a doubly-fed three-phase asynchronous motor operating at 50Hz with GTO power control, and a single-phase synchronous generator with DC excitation. The process involves stepping down power from the public 50Hz three-phase grid via a 50Hz three-phase transformer from 110kV to the operating/machine voltage (10.5kV) of the asynchronous machine. Subsequently, a single-phase 16.7Hz transformer steps up the voltage to 110kV. The scope of this tender is the procurement and supply of new replacements for the existing Ud1 (50Hz) and Uk1 (16.7Hz) transformers. This renewal is a critical step in ensuring the operational readiness and efficiency of the Hamburg-Harburg converter station, which plays a vital role in grid coupling and power conversion.
