30 CYMCAP STUDY RESULTS
31 Results from 2014 Study A full duct bank (45 cables) in isolation has a ratings of about 215A to 230A and considering the influence of the adjacent duct banks if loaded will limit the duct bank to a cable rating to between A (15%; reduction) At the section A-A location, this equates to 168MVA at 12kV for the 3 duct banks combined. Selecting a lower Tr i.e., better soil improves the ratings by about 15%. At the section A-A location, this equates to 193MVA at 12kV for the 3 duct banks combined. This prompted the consideration to use a DTS system and take soil samples for thermal resistivity measurements 31

40 40 Overview of a monitoring corridor
41 How can System Operator use temperature data? 41
42 What does the Engineer need to do? - 1 Develop a physical model describing the cable layout, cable construction and material properties Define ambient soil temperature at depth of burial Define Soil thermal resistivity 42
43 Classical Rating Analyses - 2 Perform ratings calculations with commercial software, equations coded in MathCad or Finite Element Analyses Calculate the cable sheath temperatures for measured load and compare this with the DTS data Once this has been validated then one can undertake steady-state ampacity ratings for the cable system as well as in real-time Key items to note are the knowledge of soil thermal resistivity properties and ambient soil temperature 43
44 Example of a display Screen with Dynamic Ratings Typical Display Screen 44
45 45 Results from Preliminary Analyses
46 46 Comparison of Measured and Calculated Temperatures from Model
47 Lesson learned with DTS Systems and what s next? Even solid-state drives of computer that control DTS systems seem to fail after 3-4 years Temp calibration is important to preserve the sanctity of measurements The long-term (40 year) performance of optical fibers inside a power cable remains unknown Real-time ratings usage needs careful consideration and good understanding 47
48 CONCLUSIONS DTS basics advantages/challenges and fibre placements options- pros and cons Synopsis of history of DTS usage at BC Hydro and a few case studies Potential use of DTS data by System Operators to optimize asset utilization Lessons Learned and Future applications 48
