Power Quality Audit

Power quality is of major concern to all types of industries, especially those operating with critical machinery and equipments. Poor quality of power leads to major problems like break-downs, production interruptions, excess energy consumption etc. Modern industries require automation of their operation enabling them to produce quality products and also for mass production. The conventional systems are being replaced by modern Power Electronic systems, bringing a variety of advantages to the users. Classic examples are DC & AC Drives, UPS, soft starters, etc. Since the Thyristor converter technology is rapidly gaining ground in the modern industrial plants, the power supply systems are contaminated as the ideal sinusoidal current and voltage waveforms are getting distorted.

This in turn is affecting the performance of the equipment in the electrical network, especially the
Power Factor correction capacitors.

Cholamandalam MS Risk Services offers a comprehensive power quality audits to the industries, distribution centres and commercial establishments. Power quality (PQ) consultation can help businesses prevent equipment malfunctions related to electric power anomalies. The main task of the power quality consultant is to monitor, analyze and identify power quality problems and make recommendations on how to solve them.

The basic benefits of power quality audits are:

• Savings in energy bills due to reduced losses
• Accurate measurement by installed meters
• Reduced kVA demand
• Improved system efficiency
• Better capacity utilization of network
• Better production rate and quality due to reduced interruptions
• Improved safety
• Enhanced life of electrical network and components
• Improved system power factor
  
  

Thermal Energy Audit

An Energy Audit Study helps an organisation to understand and analyse its energy utilisation and identify areas where energy use can be reduced, decide on how to budget energy use, plan & practice  feasible energy conservation methods that will enhance their energy efficiency, curtail energy wastage and substantially reduce energy costs. Cholamandalam MS Risk Services offer the following thermal energy audit services:

• Auditing of Energy Consumption (including any heat and power generated)
  
  
• Measurement of all energy flows (including testing of boiler or steam raising, heating equipment, refrigeration, etc.)
  
  
• Analysis and appraisal of energy usage.(e.g. specific fuel consumption, energy-product interrelationship).
  
• Identification of energy improvement opportunities and recommendations for energy efficiency measures and quantification of implementation costs and paybacks.
  
  
• Steam utilization audits
  
  
• Boiler and heater performance assessment and load management studies
  
  
• Performance assessment of heat exchangers, cooling towers, dryers and other thermal systems
  
  
• Performance assessment of building air conditioning and chiller plants

Our teams have hands on experience in using the following software models in thermal energy auditing programs:

• Steam System Assessment Tool (SSAT) — Estimates the impacts of key steam system improvements. Generates results detailing the energy, cost, and emissions savings that up to 16 different improvements could achieve.
  
  
• Steam System Scoping Tool (SSST) — Evaluates a facility's steam system operations and management practices against best practices
  
  
• AIRMaster+ — Assesses compressed air systems, models existing and future systems upgrades, and evaluates savings and effectiveness of energy efficiency measures.

Electrical Energy Audit

Cholamandalam MS Risk Services offer the following electrical energy audit services for industry, commercial establishments and residential buildings: Electrical load management studies Thermograpgy studies for electrical energy audits Power factor measurement and improvement studies Transformers Electrical drivers and utilities Lighting and illumination modelling and audits Electric heating applications Electrical welding applications Industrial and commercial cooling and refrigeration systems Residential, commercial and industrial air conditioning systems Cooling towers Compressors air systems Diesel generators Our teams have hands on experience in using the following software models in thermal energy auditing programs: MotorMaster+ — Identifies inefficient or oversized facility motors and computes the energy and demand savings associated with selection of a replacement energy-efficient model. Pumping System Assessment Tool (PSAT) — Helps user identify energy savings opportunities in pumping systems and quantifies those opportunities in both rupees and electrical energy. Fan System Assessment Tool (FSAT) — Assesses the efficiency of fan system operations. Identifies savings opportunities, analyzes system data to rate efficiency, calculates energy savings, and identifies fan systems that are not operating at best capacity.

Energy Demand and Load Management Studies

The demand charges constitutes a considerable portion of the electricity bill, thus demanding an integrated load management system to effectively control the maximum demand. The state electricity boards uses different power tariff structure to influence end user in better load management through measures like time of use tariff, penalties on exceeding maximum demand, night tariff concession etc., Cholamandalam MS Risk Services offer the following services under energy demand management studies: Transformer Load Management studies - average & maximum Loading, loss estimation based on load loss factor, voltage deviation assessment from rated voltage Evaluation of current energy metering scheme for better accountability Analysis of electricity distribution system- phase imbalances and harmonics Generation of load curve to predict patterns of drawl, peaks and valleys and energy use trends Options to rescheduling of loads to reduce the maximum demand Options to reduce reactive power compensation - improving Power Factor, selection and Location of capacitors and performance assessment of capacitors

Building Energy Audits and Management

The energy audit in a building is a feasibility study. For it not only serves to identify energy use among the various services and to identify opportunities for energy conservation, but it is also a crucial first step in establishing an energy management program. The study should reveal to the owner, manager, or management team of the building the options available for reducing energy waste, the costs involved, and the benefits achievable from implementing those energy-conserving opportunities (CEOs). It begins with a detailed, step-by-step analysis of the building's energy use factors and costs, such as insulation values, occupancy schedules, chiller efficiencies, lighting levels, and records of utility and fuel expenditures. It includes the identification of specific ECOs, along with the cost-effective benefits of each one. The completed study would provide the building owner with a thorough and detailed basis for deciding which ECOs to implement, the magnitude of savings to be expected, and the energy conservation goals to be established and achieved in the energy management program. The second stage is to improve efficiency of energy conversion equipment and to reduce energy use by proper operations and maintenance. ECOs would include the following: Building equipment operation, Building envelope, Air-conditioning and mechanical ventilation equipment and systems, Lighting systems, Power systems, and Miscellaneous services Our teams are conversant with the following software applications: Building energy simulation using Visual DOE Building lighting energy modeling Building indoor ventilation modeling using CFD models
