Foreword
This standard replaces GB/T 13462-1992 "Enterprise Power Transformer Economic Operation Guide."
This standard compared with GB/T 13462-1992 main changes are as follows.
--- Delete the original standard name of the "mining industry" and "guidance."
--- The scope of the words "This standard applies to power generation and supply, economic operation and management of power units running power transformers, as well as
Units of new construction, renovation configuration of power transformers. "
--- Deletes from the original 3.9 "active load rate" as used herein, an increase of "Reactive economic equivalent", "phase unbalanced load loss coefficient", "non
Zone economy "," economic load allocation "," economic capacity "," Economic several "and other terms.
--- Cancel the original basic formula of the clauses, the basic formula into Appendix A, and adds three-winding transformer in Appendix A
The basic formula.
--- In economic operation mode selection, increase the selection of parallel operation of three-winding transformer economic operation mode.
--- In determining the economic performance in the region, adding "economic load factor", "three-winding transformer the best economic load factor" and the "three around
Group transformer economic operation zone. "
--- Increase the transformer load regulation of content.
--- Canceled reg former economy electricity savings calculations.
--- Added "phase unbalanced load transformer loss factor" and "Reactive economic equivalent", "basic formula" and "case" four
appendix.
Appendix A of this standard is a normative appendix, Appendix B, Appendix C, Appendix D and Appendix E is an informative annex.

3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Ensuring safe and reliable operation and power supply to meet demand, based on the rational allocation by the transformer, the transformer operation mode
To optimize the selection, implementation of the economic adjustment transformer load, thereby minimizing the power loss of the transformer.
3.2
ΔPZ
Operating Transformer active power loss and reactive power consumption because it increases the active power grid by the sum of the loss.
3.3
ΔPZ%
Its input transformer integrated power loss ratio of active power percentage.
3.4
KQ
The amount of loss caused by the active power grid to increase or decrease the transformer reactive power consumption increases or decreases by 1kvar.
3.5
Within a certain period of time, depending on the ratio of the power transformer rated capacity of the transformer average output.
