Power Quality and Energy Management 8am – 12pm
Overview of Article 750
Installation and Operation of Energy Management Systems; Loads not to be overridden; Assessment, Control, Monitoring, and Management; Correction, Recovery, Improvement, and Control.
Utility Energy Quality
Clarifying and explaining the questions of utility energy quality. Age of delivery system from the utility; environmental impacts affecting delivery; current voltage and sign wave under load; is there lead or lag in the phase sign wave; connection termination provisions; conductor properties provided; is delivery a shared system by utility.
Six Phases of the Process Flow
Assessment of Utility and Feeder; Analysis of Overall System; Review, Cost, and Outcomes; Recovery, Methods, Tasks, and Materials; Payback for Recovery Process; Control and Monitoring.
Eight Fundamentals of the Process
Overview of assessment of system; Analysis of supplied energy or power delivery; loads and utilization equipment; metering and distribution provisions; wiring methods assessment; system power study; system correction analysis; corrective actions and materials.
System Assessment Factors
Quality of delivered energy; distribution method within system; utilization equipment within system; installation methods; heat signature of components and system; distances of distribution and utilization; age of system and components; HVAC, motors, lighting, and appliance loading
Power Quality and Thermal Imaging
Use of thermal imaging for system assessment; discovery and correct aspects of overall system improvements; support applications with imaging cameras provide time dating video assessment for condition of motors; online training or formal certification programs though manufacturer.
Properties of Resistance
Current flow from utility provider is measured in resistance; assessment of conductor resistance and adjustment can provide large adjustment factors in equipment loads; Chapter 9, Tables 8 and 9 of NEC for basic resistance of conductors; voltage drop analysis providing information in the resistance assessments.
Methods of Installation
Evaluation of existing installation methods; assessment of terminations; review overcurrent and short-circuit applications; bonding and grounding vs fault pathways; raceways and junction boxes evaluating; condition of feeder and distribution equipment.
Delivery vs Usage
System usage in combined overall loads; amount of energy used from delivery versus loads; loads that can be managed or scheduled; percentage of loss and recovery; impact of loads due to condition or performance; impact of installation methods existing; accurate calculation of kilowatt usage to loss.
System Analysis Results
Correction and update of installation methods; reduction of resistance within system; upgrade of equipment and/or controlled or monitored; shedding of loads and scheduled usage; reduction of heat within system; improvement of distribution; correction of utility delivery; increased kilowatt to usage rating; economic recovery of cost through time-based payback.
Format collected information for overall system assessment; identify areas for improvement or corrective actions; list upgrade options for improved performance and reductions; develop an equipment and material list from survey assessments; develop and produce a recovery plan of action-by-action phases; assess and overview of recovery and payback timeline; prepare a recovery presentation with plan of action assessments; recovery presentation with timeline, cost, and payback conclusions.
