三相交流系统中的短路电流 - 第2部分：用于短路电流计算的电气设备数据

SHORT-CIRCUIT CURRENTS IN THREE-PHASE AC SYSTEMS – Part 2: Data of electrical equipment for short-circuit current calculations

1 General

1.1 Scope and object

This part of IEC 60909 comprises data of electrical equipment collected from different countries to be used when necessary for the calculation of short-circuit currents in accordance with IEC 60909-0.

Generally, electrical equipment data are given by the manufacturers on the name plate or by the electricity supplier.

In some cases, however, the data may not be available. The data in this report may be applied for calculating short-circuit currents in low-voltage networks if they are in accordance with typical equipment employed in the user's country. The collected data and their evaluation may be used for medium- or high-voltage planning purposes and also for comparison with data given by manufacturers or electricity suppliers. For overhead lines and cables the electrical data may in some cases also be calculated from the physical dimensions and the material following the equations given in this report.

Thus this technical report is an addition to IEC 60909-0. It does not, however, change the basis for the standardized calculation procedure given in IEC 60909-0 and IEC 60909-3.

1.2 Normative references

The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

IEC 60909-0:2001, Short-circuit currents in three-phase a.c. systems – Part 0: Calculation of currents

IEC 60909-3:-1, Short-circuit currents in three-phase a.c. systems – Part 3: Currents during two separate simultaneous line-to-earth short-circuit currents and partial short-circuit currents flowing through earth

2 Data for electrical equipment

2.1 General

The data presented are necessary for the calculation of short-circuit currents. They are sometimes presented in the form of curve sheets and sometimes in the form of examples in tables. In the case of easy equations they are given for the calculations of positive-sequence and zero-sequence short-circuit impedances for overhead lines and cables.

1 To be published.

In all, 15 National Committees provided information in response to a questionnaire sent out before the first edition of this report. Table 1 of the first edition of this report is given in Annex A.

In some cases, average values or characteristic trends as function of rated power, rated voltage, etc. are given.

2.2 Data of typical synchronous machines

Characteristic data of synchronous machines are listed in Table 1. The reactances are given as relative values related to Z_RG = U_RG²/S_RG (see IEC 60909-0). Sometimes they are given in %.

In Figure 1 the sub-transient reactances of synchronous machines (generators, motors and condensers) in the direct axis of 50 Hz or 60 Hz machines are plotted as a function of the rated power.
