HFIDTC/WP1.1.3/10 Version 2/ 31 October 2005 Flowchart START Define scenario(s) under analysis Select appropriate CDM probes Select appropriate SME(s) Ask SME to give a description of incident Divide the incident into key phases Take the first/next incident phase Use probes to gather information for each incident phase Are there any more incident phases Transcribe data Construct CDM output tables STOP 71
HFIDTC/WP1.1.3/10 Version 2/ 31 October 2005 Example The following example is taken from a CDM analysis that was conducted in order to analyse C4i activity in the civil energy distribution domain (Salmon et al 2004b). The scenario under analysis involved the switching out of three circuits at Barking 275Kv, 132Kv and 33Kv Substations. Circuit SGT5 was being switched out for the installation of a new transformer for the nearby channel tunnel rail link and SGT1A and 1B were being switched out for substation maintenance. For the CDM analysis, the control room operator co-ordinating the activity and the senior authorised person at Barking substation who conducted the activity were interviewed. The set of CDM probes used are presented in Table 9. The scenario was divided into four key phases: First issue of instructions • Deal with switching requests • Perform isolation • Report back to network operations centre The CDM output is presented in Table 25 to Table 28. Table 25 - Phase 1: First issue of instructions Goal Specification Cue identification Expectancy Conceptual Model Uncertainty Information Situation Awareness Situation Assessment Options Stress Choice Analogy Establish what isolation the SAP at Barking is looking for. Depends on gear Don’t Believe It (DBI) alarm is unusual – faulty contact (not open or closed) questionable data from site checking rating of earth switches (may be not fully rated for circuit current – so additional earths may be required. Check that SAP is happy with instructions as not normal. Decision expected by DBI is not common. Recognised instruction but not stated in WE1000 – as there are not too many front and rear shutters metal clad switch gear. Confirm from field about planned instruction – make sure that SAP is happy with the instruction. Reference to front and rear busbars. WE1000 procedure Metal clad switchgear Barking SGT1A/1B substation screen SAP at Barking Ask colleagues if needed to No alternatives N/A WE1000 – need to remove what does not apply Could add front and rear busbar procedures Best practice guide for metal clad EMS switching 72
