Scope

Scope: This standard specifies the basic principles, feasibility analysis, equipment evaluation of generator units, modification content, performance requirements of phase shifters, and testing and acceptance for the implementation of adding phase shifter function to thermal power units. This standard applies to the modification of two-pole non-excited hydrogen-hydrogen cooled thermal power units with self-excited excitation mode, with a single unit capacity of 100MW or above, to add phase shifter function. Other types and capacities of units may refer to this standard for implementation.
