4. TECHNICAL PARAMETERS AND SCOPE OF THE

CONTRACT

4.1.SYSTEM DESCRIPTION:

A 30 KWp grid interactive solar power plant shall supplement during the day time the

electricity needs of the premise by using clean and renewable solar energy. A small 6 KW wind

operated electricity generator with a battery bank will also be installed to provide power to meetessential load during power failure. Thus, the system installed shall be a Grid-Solar- Wind hybrid

system.The D.C. power generated from solar PV array shall be converted to AC power by an inverter

and the system shall be connected and synchronized to the supplier grid system through a Power

Conditioner Unit (PCU). Power generated from the solar PV system during the daytime is

utilized fully for meeting electricity requirement of Governors residential complex and excess

power, if any, shall be fed to grid. In cases, when solar power is not available (i.e at night) or is

not sufficient due to cloud cover etc. the electrical loads are served by drawing power from thegrid.

4.2.LOGIC OF OPERATION OF THE GRID- SOLAR- WIND HYBRID SYSTEM

The balance of system in the Power Conditioning Unit will be designed in such a way that it

always give preference to the Solar Power and will use Grid/DG power only when the Solar

Power is insufficient to meet the load requirement. Any excess requirement will be drawn from

the grid/DG power. On the other hand any excess solar generation will be fed to the grid .The

aggregate power drawn from the grid will be recorded by Net Metering from i.e export and

import metering arrangement and billed by the distribution utility accordingly.

The battery bank for essential power supply will be normally charged by the wind generator .But

the charge controller will also have a supply from the grid solar PV system and will charge the

battery when charging from the wind generator will not adequate and voltage of the battery bank

falls below a predetermined value.

4.3. EXISTING POWER SUPPLY SYSTEM AND PHYSICAL INTEGRATION OF

RENEWABLE ENERGY SYSTEM TO EXISTING POWER SUPPLY SYSTEM:

The power supply to the Raj Bhavan premises is from the power utilitys grid system through

two 250 KVA transformers. There are two standby 250KVA diesel generators to provide

electricity during power failures / power cuts.

One transformer supplies the Governors residence, the guest house and Governors personal

office. While the other transformers supply the Governors secretariat and Darbar Hall. It is

proposed to connect the solar PV system to the Governors residence power supply
