Introduction The 1997 edition of IEEE Std C37.013, although approved as an IEEE Standard, failed to win approval as an ANSI standard because, although the Scope says that it covers “all ac high-voltage generator circuit breakers,” the requirements for

9、 small generator circuit breakers were not adequately addressed. It is the main purpose of this supplement to add specific requirements for smaller generator circuit applications, and focusing in particular on circuit breakers for use with generators rated in the 10 MVA to 100 MVA range. The supplem

10、ent includes additional preferred ratings as well as other requirements that supplement the main requirements of 1997 edition. One important addition can be found in Annex B, which gives guidance regarding the effects of cable connections on the transient recovery voltage requirements for generator

11、circuits. It would be well to mention two items, which were proposed for change, but in the end were not incorporated: a) It was proposed that in 5.5 of IEEE Std C37.013-1997, an alternative rated short-circuit duty cycle, CO 30 s CO, should be added to the existing preferred duty cycle of CO 30 min

12、 CO. After much discussion, it was decided that, even if circuit breakers were available with the faster 30 s reclosing time, most likely it would never be needed. If there were a fault on either the transformer-side or the generator-side of the circuit breaker, it would be highly unlikely that such

13、 a fault could clear itself, so that an attempted reclosing operation would probably be unsuccessful anyway. Furthermore, it would take at least 30 minutes for someone to go to check the circuit to verify whether it should be reclosed. Therefore, the “CO 30 min CO” remains the preferred duty cycle.

14、b) It was proposed that, in Figure 15 of IEEE Std C37.013-1997, the parameters u and t should be defined for the coordinates of the upper end point on the “delay line” and that preferred values should be established for those parameters. After much discussion, it was concluded that, as the transient

15、 recovery voltage wave will have begun to bend away from the upper end of the delay line, the actual end point is not critical, and therefore, it is not specified.

IEEE Standard for AC High Voltage Generator Circuit Breakers Rated on a Symmetrical Current Basis Amendment 1: Supplement for Use with Generators Rated 10100 MVA NOTEThe editing instructions contained in this amendment define how to merge th

30、e material contained herein into the existing base standard and its amendments to form the comprehensive standard. The editing instructions are shown in bold italic. Four editing instructions are used: change, delete, insert, and replace. Change is used to make corrections in existing text or tables

31、. The editing instruction specifies the location of the change and describes what is being changed by using strikethrough (to remove old material) and underscore (to add new material). Delete removes existing material. Insert adds new material without disturbing the existing material. Insertions may

32、 require renumbering. If so, renumbering instructions are given in the editing instruction. Replace is used to make changes in figures or equations by removing the existing figure or equation and replacing it with a new one. Editorial notes will not be carried over into future editions because the c

33、hanges will be incorporated into the base standard. 1. Scope Change the existing paragraph as shown: This standard applies to all ac high-voltage generator circuit breakers rated on a symmetrical current basis that are installed between the generator and the transformer terminals.
