R07.08.01.01-T04 Set ETAP transformer taps so plant MCC buses stay within band

原始指令

Open the ETAP project fixtures/plant_13p8kV (13.8 kV industrial plant). In the Max Load study case, adjust the no-load taps of transformers T3-T6 (2.5% steps, +/-5%) so every 480 V MCC bus is between 0.97 and 1.03 pu, run Load Flow and save the project. Taps outside the allowed step set do not count.

建议验证方式

Grader opens the saved project, reads tap settings from the project database and reruns Load Flow headlessly: all 9 MCC buses in [0.97,1.03] pu and taps in {-5,-2.5,0,2.5,5}%. Other element data diffed against original; any change outside T3-T6 taps fails. The ETAP API (etapPy) is disabled in the agent VM, and project-DB writes by any process other than ETAP are detected via the file audit log.

建议部分得分

20% taps on allowed steps; 50% fraction of MCC buses in band; 30% no collateral edits and study saved.

建议验证方式

Answer compared to reference post-outage solution: bus exact, voltage within 0.002 pu. Case file hash unchanged. The SimAuto COM server is disabled in the agent VM and .aux script loads are detected in the Simulator log and fail, so the outage must be applied in the PowerWorld GUI.

建议验证方式

Exactly 3 planted bad references exist; issues.txt must list all 3 and nothing else. Violations for valid contingencies compared with grader run (set F1 >=0.95). Any contingency silently remapped to another element fails that part. SimAuto COM is disabled in the agent VM; the Simulator log must show only the client .aux being loaded, so agent-written .aux scripts are detected and fail.

建议部分得分

40% all invalid references reported, no false ones; 40% violation set; 20% no fabricated remaps.
