Short-Circuit Analysis For load and generator connection, all the generators in the Study Area should be on-line. Include the short-circuit analysis for the preferred alternative amoung the listed alternatives in Section 5.2. If connection alternatives will impact short-circuit current, provide the results, include the short-circuit analysis for the studied alternative. Explain if the short-circuit current levels would not be materially changed or not. Highlight the short circuit current levels which are above 90% of equipment rating. Market participants can approach the AESO for advice with respect to long-term anticipated short circuit levels and can collaborate with the AESO on a system-based solution if a more locally-based solution cannot solve it. Pre-Project Provide pre-Project short-circuit current levels for the studied alternative. Use a table. 8.11: Summary of Short-Circuit Current Levels Pre-Project (Year 20XX) – Positive Sequence Zero Sequence Base 3-Φ 1-Φ Substation Name and Fault Thevenin Source Thevenin Source Voltage Voltage Number Impedance (R1+jX1) Impedance (R0+jX0) (kV) (kA) (kA) (kV) (pu) (pu) Table 8.12: Summary of Short-Circuit Current Levels Pre-Project (Year 20XX [Year of Proposed – Connection + 10 Years]) Positive Sequence Zero Sequence Base 3-Φ 1-Φ Substation Name and Thevenin Source Thevenin Source Voltage Voltage Fault Fault Number Impedance (R1+jX1) Impedance (R0+jX0) (kV) (kA) (kA) (kV) (pu) (pu) Post-Project Provide post-Project current levels for the preferred alternative.
