UTCC 2014 - Battery Backup Workshop - Dakx Turcotte

744 views

Published on

This is the battery backup workshop presentation that I did at Utilities Telecom Council of Canada (UTCC) 2014. This workshop introduced you to a critical aspect of telecommunications reliability: battery backup. The objective of the workshop is to make sure you always have enough battery backup.

The workshop is split in three parts:

Part 1 will introduce you to the physics of batteries and the reasons why they fail.

Part 2 will introduce you to battery backup from the perspective of a field operations technician and manager: how to calculate battery backup in terms of outage, how to perform preventive maintenance to help increase battery lifetime, which tests to perform to detect failing batteries, the different tests and their pros and cons and new NERC’s regulation (PRC-005-02) and their impact on field operations workload.

Part 3 will introduce you to battery backup from the perspective of planning and engineering: how to plan for enough battery backup, which records should you have to comply with NERC’s guidelines, how to update records at a regular interval to estimate if battery backup is still sufficient, which data should you use to update records and more.

  66. 66. German physicist. High school teacher. Began his research with a recent invention by Italian Count Alessandro Volta. Using equipment of his creation, he determined that there is a: direct proportionality between the potential difference applied across a conductor and the resultant electric current. 66 2014 Canadian Utilities IT & Telecom Conference | September 23-26 | Calgary, Alberta ‹#›
  67. 67. Who is Georg Simon Ohm (17 March 1789 – 6 July 1854) 67 2014 Canadian Utilities IT & Telecom Conference | September 23-26 | Calgary, Alberta ‹#›
  68. 68. OHM’S LAW Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points, and inversely proportional to the resistance between them. 68 2014 Canadian Utilities IT & Telecom Conference | September 23-26 | Calgary, Alberta ‹#›
  69. 69. CONDUCTANCE Conductance is a measurement of the plate surfaces available for chemical reaction. High relative conductance is a reliable indication of a healthy battery. Conductance declines as the battery fails. ! By applying an electrical voltage of a known frequency and amplitude across the jar and measuring the current that flows in response to it. The conductance (acceptance) is the ratio of the AC test current impressed on the jar that is in-phase with the AC voltage, compared to the AC voltage producing it. ! DC Resistance: Short duration DC load on the cell/unit to measure step change in current and voltage. By dividing the change in voltage by the change in current, a DC resistance is calculated using Ohm's law. 69 2014 Canadian Utilities IT & Telecom Conference | September 23-26 | Calgary, Alberta ‹#›
  70. 70. IMPEDANCE Performed by sending an electrical current of a known frequency and amplitude, across the cell/unit/block and measuring the AC voltage drop. ! Compute the resulting impedance using Ohm's law. 70 2014 Canadian Utilities IT & Telecom Conference | September 23-26 | Calgary, Alberta ‹#›

  90. 90. AS A RULE OF THUMB Validated ETA - Validated BRT = Time to get to a site & react/repair 90 2014 Canadian Utilities IT & Telecom Conference | September 23-26 | Calgary, Alberta ‹#›
  91. 91. VALIDATE BRT A validated Battery Reserve Time (BRT) is a key metric field technicians need to react in optimal fashion in case of outage or equipment failure. • Get there as soon as necessary • Bring the right equipment (generator, generator connector fitting plug and cable, replacement parts) • Do as few truck rolls as possible • Keep the site up 91 2014 Canadian Utilities IT & Telecom Conference | September 23-26 | Calgary, Alberta ‹#›
  92. 92. VALIDATE BRT There are 4 steps needed to validate BRT: (1) look for the last available LOAD reading (2) look for records of exact battery MODEL installed on site (3) find battery model’s DATASHEET with specific capacity measurements at specific end-voltage value (4) use rule of thumb or PEUKERT to estimate BRT 92 2014 Canadian Utilities IT & Telecom Conference | September 23-26 | Calgary, Alberta ‹#›

  94. 94. German scientist. In 1897, presented his “law” that expresses the capacity of a battery in terms of the rate at which it is discharged. As the rate increases, the battery's available capacity decreases. 94 2014 Canadian Utilities IT & Telecom Conference | September 23-26 | Calgary, Alberta ‹#›
  95. 95. Who is Peukert 95 2014 Canadian Utilities IT & Telecom Conference | September 23-26 | Calgary, Alberta ‹#›
  96. 96. PEUKERT Manufacturers rate the capacity of a battery with reference to a discharge time. A battery might be rated at 100 Ah when discharged at a rate that will fully discharge the battery in 20 hours. In this example, the discharge current would be 5 amperes. If the battery is discharged in a shorter time, with a higher current, the delivered capacity is less. 96 2014 Canadian Utilities IT & Telecom Conference | September 23-26 | Calgary, Alberta ‹#›
  97. 97. PEUKERT What you need to know: (1) The law is not a law, it’s a recognized concept. (2) Peukert determines a “k” factor to apply to a battery technology. For telecom batteries: 1.2. 97 2014 Canadian Utilities IT & Telecom Conference | September 23-26 | Calgary, Alberta ‹#›
