Advance Electrical Design & Engineering Institute Electric power transmission is the bulk transfer of electrical energy, a process in the delivery of electricity to consumers. A power transmission network typically connects power plants to multiple substations near a populated area.

The wiring from substations to customers is referred to as electricity distribution, following the historic business model separating the wholesale electricity transmission business from distributors who deliver the electricity to the homes.

•Provide an alternative path for the fault current to flow so that it will not endanger the user •Ensure that all exposed conductive parts do not reach a dangerous potential

•Maintain the voltage at any part of an electrical system at a known value so as to prevent over current or excessive

voltage on the appliances or equipment.

•Transmission

•Substations & Power Generations •Telecommunication

•Transformer Neutral Earthing •Lightning Arrestor Earthing •Equipment Body Earthing •Water Treatment Plants •Heavy Industries

•College, Hospitals, Banks •Residential Building

breakers, relay, etc.

To isolate the fault or overloads.

Protection

Prevent injury to personnel

Minimize damage to components

Quickly isolate the affected portion of the

system Coordination

Limit the extent and duration of service

interruption

Selective fault isolation Provide alternate circuits

Relay Coordination:

 50,51,50N (over current and earth fault Relay) 27,59,81(O),81(U)(Under voltage & Over

Voltage, , Under Frequency & Overfrequency)

Transformer Protection (Buccholz Relay, WTI)

Study Procedure

# Prepare an accurate one-line diagram (relay diagrams) # Obtain the available system current spectrum # Determine the equipment protection guidelines # Select the appropriate devices / settings

# Plot the fixed points (damage curves, …) # Obtain / plot the device characteristics curves #Analyze the results

Ensure that motor will start with voltage drop If Tst<Tloadat s=1, then motor will not start

If Tm=Tloadat s<sr, motor can not reach rated speed Torque varies as (voltage)^2

Ensure that voltage drop will not disrupt other loads Utility bus voltage >95%

3% Sag represents a point when light flicker becomes

visible

5% Sag represents a point when light flicker becomes

irritating

MCC bus voltage >80%

Generation bus voltage > 93%

Ensure motor feeders sized adequately (Assuming 100% voltage at Switchboard or MCC)

LV cable voltage drop at starting < 20% LV cable voltage drop when running at

full-load < 5%

HV cable voltage drop at starting < 15% HV cable voltage drop when running at

full-load < 3%

Maximum motor size that can be started

across the line

Motor kW < 1/6 kW rating of generator

(islanded)

For 6 MW of islanded generation, largest

Potential of solar energy

What is Photovoltaic (PV)?

Photovoltaic means turning daylight directly into dc electricity

Done by photovoltaic cells (PV cells), assembled into PV modules

 There are no moving parts

 There is no 'fuel', apart from daylight

 The modules need no maintenance

 In principle, almost indefinite lifetime

PV works with both direct sunlight and indirect daylight (more light = more power) Central power plant Offices Houses Storage Microturbines Fuel cells Industrial plants Wind turbines Virtual power plant CHP PV power plant Central power plant Offices Houses Storage Microturbines Fuel cells Industrial plants Wind turbines Virtual power plant CHP PV power plant

Photovoltaic is the most elegant way of producing electricity
