India's new capacity 17 in 2018. 6 gw renewable energy accounted for over 7

(4) inverter, is to convert direct current (dc) to alternating current (ac) devices. Due to the solar battery and battery is a dc power supply, load is ac load, inverter is indispensable. Inverter according to the operation mode, can be divided into independent operation inverter and grid inverter. Independent operation inverter is used to run the solar cell power generation system, load power supply for independence. Grid inverter is used in the parallel operation of the solar cell power generation system. According to the output waveform, the inverter is divided into square wave inverter and sine wave inverter. Square wave inverter circuit is simple, low cost, but big harmonic component, generally used for several hundred the following system and requirements for harmonic is not high. Sine wave inverter cost is high, but can be applied to all kinds of load.

solar photovoltaic net news: according to the latest statistics show that India added 17 in 2018. 6 gigawatts of electricity ( Net) , of which 74% based on renewable energy technologies ( Mainly solar power) , a record high, at this point, become the most environmental protection so far new capacity in 2018 a year.

in particular, India new power capacity to 17 in 2018. 6 gw, four of them. 1 gw from fossil fuels, Including coal, oil, etc. ) , about 435 megawatts from large hydropower, 13. 1 gw from renewable energy technologies, including solar power generation capacity of 8. 9 gw, wind power project 2. 2 gw.

as a result, the output increases, the solar energy accounted for 50% of the share, and wind power accounted for 12%. Fossil fuels to cut to 24%, but slightly higher than the 21% in 2017.

in the second half of 2018 the net capacity of 12 increase rate from the first half of 2018. 7 gw fell sharply, but with the second half of 2017 increased production capacity ( 3. 3000 megawatts) Compared to improve slightly. Fossil fuel industry only increases the net capacity of 335 megawatts.

in the second half of 2018, renewable energy in the total net increase in the proportion is as high as 93%, a net increase in 4. 4, 9000 megawatts of capacity. 6000 megawatts from renewable energy capacity. 59% of solar, wind is 15%, fossil fuel is 6%.

a substantial rise last year of renewable energy capacity reflects the share of low-carbon electricity. The share of renewable energy power generation in India during the period of January to November 2018 all-time high reached 9%, waiting for the final figure in December. In the third quarter of 2018 wind energy and renewable energy technologies at a record high as a share of the overall capacity, 8, respectively. 2% and 11. 9%.
