7  INTRODUCTION  OBJECTIVE  THINK TANK SLD  COMPONENTS  SYSTEM WORKING PLANS Hybrid Solar Project

8 Introduction In solar power plant, the normal efficiency is up to 10-15%. The efficiency of solar power plant changes due to the change in insolation. So, the output of the plant also varies. The maximum power is delivered only in the peak hours of the insolation i.e. from 12 p.m to 3 p.m. This will result in moderate unit generation per day which directly impacts on the output of the plant. And during sudden loading i.e. the load on the plant is more than the capacity of the plant. Therefore the plant cannot reach or meet the required demand due to high demand from load side, high amount of current drawn from the source.

9 Introduction A synchronous motor is installed in the system to maintain the consistency in the power supply to give out required power according to the demand. This project will give out detailed description of soft drive & the synchronous motor application as well as their performance and plant output before & after installation.

10 Objective  To Get Continuous Electricity Output Through Solar Photovoltaic Plant  To Maintain Grid Synchronism & Increasing Reach  To Achieve Fastest Payback Period  To Get More No. Of Units In A Day, Ultimately Which Will Convert Into More Income

14 Operation of the Plant SOLAR PLANT : During day time, based on insolation the generated power is collected by the DC distribution box & fed to the inverter which converts the power from DC to AC. VFD : A VFD is installed at the output side of the inverter. It controls as well as monitors the voltage & frequency levels of the synchronous motors. SYNCHRONOUS MOTORS : Two synchronous motors are installed parallel in the plant which makes them to operate at same voltage levels. Squirrel cage is attached to maintain same direction of rotation. One motor will be loaded by a generator & the other one will be kept at no load, which in turn makes it to generate as much power as the motor on load consumes. Half of this power will be fed to the battery & remaining half will be supplied to the grid.

15 ALTERNATOR : An alternator is connected to the synchronous motor 1. The rating of the motor is 500 kw. By considering losses, we have the output of 400 kw which is directly fed to the grid. BATTERY BANK : The battery bank is of 600 kw. The battery bank is a back up power to the hybrid solar plant. During the day hours the battery bank is charged through the synchronous motor. The synchronous motor which is on no load feeds 50% of power to the battery which is controlled by automation. This power is used to run the plant during night hours. CHARGE CONTROLLER : The charge controller is the controlling device at the battery bank to maintain moderate operation & balanced voltage & power levels during faulty condition.

16 How Our Proposed System Works ?

17 Case – 1 ( Day Cycle ) The solar plant will generate electricity during the day time & it is fed to run the synchronous motors via the variable frequency drive, the variable frequency drive will control the speed of the synchronous motor by varying the frequency & voltage levels as well as maintains power quality. The unloaded synchronous motor caters its 50% power to the battery bank via charge controller & 50% to yard. Whereas the loaded motor will directly feed the power to the grid by means of an alternator. Automation is provided to maintain unidirectional operation of the motors. The VFD will monitor the voltage, frequency & quality of power at load.

19 Case – 2 ( Day Cycle ) During the night hours, the supply changes from solar panels to battery bank by means of automation. Since the battery bank is charged at day time, this charged power of battery bank is used during night hours to maintain the continuity of power generation.

21 Calculation CASE 1 : NORMAL CASE Consider a 1MW solar plant. for average peak sun hours taking reference So, considering average peak sun hours at any particular location is 5 hours Duration of energy production in day time : 5 hours Therefore the generation = 1000 kw/hr, Which is 1000 units/hr Therefore for 5 hours, it will be 5000 units. That will make 5000 units a day.

22 CASE 2 : DURING DAY TIME After installing synchronous motors & alternator along with soft drive in plant & a battery bank. Let us take : 1) two synchronous motors of 500 kw 2) alternator of 500 kw 3) battery bank of 600 kw When two synchronous motors are started by a soft drive; they will run at synchronous speed on no load. Let motor 1 is loaded with alternator & motor 2 is kept on no load. Consequently the amount of power consumed by generator will be the same amount of power generated by the motor which is on no load. Now, taking losses into account for the alternator; I/P of the alternator = 500 kwh O/P of the alternator = 400 kwh The synchronous motor which is on no load generates 400 kwh power.

23 Out of this 400 kwh; 200 kwh is fed to the grid & 200 kwh is supplied to the 600 kw battery bank. Eventually, during day time, Power generated by solar panels = 500 units/hr Power generated by synchronous motor which is on no load = 400 units/hr Power generated by alternator = 400 units/hr Therefore, total power generated = 1300 units/hr So, aggregating for 10 hours = units The plant generates units during DAY hours.

24 CASE 3 : DURING NIGHT TIME The power generated by solar panels during night hours is nearly zero. Therefore, the synchronous motors will run by 600 kw from the battery bank. As the synchronous motor gets loaded with the alternator of 500 kw; energy generated by synchronous motor operating at no load will be 400 kwh. Supply from battery bank = 600kw Alternator O/P = 400 units/hr Synchronous motor O/P = 400 units/hr Total power generated = 800 units/hr For 14 hours of night; Total power generated = 14 * 800 = units The plant generates units during night hours.

25 THEREFORE TOTAL ENERGY GENERATED IN 24 HOURS = Power generated during day time (10 hours) + Power generated during night time (14 hours) = = units For 30 days; total power generation = units For 300 days; total power generation = units Total power generated in 24 hours is units.

26 Conclusion This is a kind of concept which helps us to achieve the productivity by using hybrid technology. Application engineering is the main cause to make us able to achieve Excellency in techno-commercial achievement. In brief we like to state that it is very good usage of solar concept with tesla-nikola coil. The kind of generation will be round the clock for 24 hours. Kind of overloading spikes & dips at both the ends can be taken care. Even though weak sun rays, tracker positioning time, and kind of sudden load in peak time will be Cater. Smooth quality supply is achieved. The return over investment will be 36 months to 48 months. We can achieve our common goal. “IT IS NOT IDLE ONLY WHICH IS NOT IN USE! THE THINGS CAN BE CONSIDERED IDLE WHICH CAN BE BETTER UTILIZED!!”
