Example four: existing technology electrical network situation: spike accounts for 15～25%, and electric weight accounts for 3～7%; Waist peak load accounts for 15～20%, and electric weight accounts for 12～17%, and basic lotus accounts for 60～70%, and basic carrying capacity accounts for 75～80%.(seeing 25 pages of Chinese electric industry 92 years 2 phases " electrical network constitutes with installation ")
The existing every province of technology electrical network is for peak regulation, needs to raising 2,000,000 kw peak loads as late peak, and electrical network need be left the 2000000 kw fired power generating unit peak regulation that comes out.Because the existing comprehensive peak modulation capacity of technology fired power generating unit only is 20～30%.Because what existing technology electrical network was the most scarce is peak load 4 hours every days; as eBf among the figure and exf; because hour ability band at full capacity surplus start reached 10 during the cold machine of existing technology fired power generating unit; and the start of large electric power plant unit will be thrown tens tons of diesel oil and be entered and could leave band to fired power generating unit at full capacity; so the thermoelectricity of 2,000,000 kw only be for 4 hours every days peak regulation need leave, all the other 20 hours electrical networks do not need thermoelectricity 2,000,000 kw to shut down, and give the water power on-load.Thermoelectricity not only burns coal power generation, and should give the load of water power band of electrical network and thermoelectricity cannot stop and taken, and just causes electrical network water power 1,400,000 kw can only not abandon water because of thermoelectricity can stop any more the electricity consumption of electrical network no user.In sum, existing technology electrical network coal burns in the same old way, and water is abandoned in the same old way, and user's short of electricity in the same old way, the whole nation is the present situation of short of electricity coal in the same old way.
Difference of the present invention is that to offer high prices for local water power 2,000,000 kw every day be electrical network to raising 4 hours peak loads.As scheme eBf and exf shows.One past of peak load of grid, 4 hours every days.Local water power 2,000,000 kw shut down 20 hours; for electrical network is filled out paddy; the place utilizes each to economize hundreds of to the retaining of several thousand reservoir low ebbs; completely send out 4 hours again during second day peak; annual to send out the peak electricity; local water power was sent out 24 hours basic lotus water yields in one day and is become and send out the present invention's peak regulation 6 day 4 hours every day load, and local water can be than the annual pilosity of existing technology tens days to the hundreds of sky.Because be peak load regulation network 4 hour with local water power every day of the present invention, the electrical network 2,000,000 kw thermoelectricitys peak regulation of just need not starting shooting need not fire coal, has saved electric coal; Thermoelectricity does not account for low ebb and loads behind the 1400000 kw water power, and the present invention just can promote electrical network water power multiple 24 hours energy output 1,400,000 kw every day every day, and the water power generating need not be coal-fired, and thermoelectricity shuts down that do not generate electricity need not be coal-fired, has saved electric coal; Come to be peak load regulation network 4 hours that the present invention just can promote existing technology electrical network 3,400,000 kw units need not burn coal, has saved electric coal so only need offer high prices for the local water power of 2,000,000 kw every day of the present invention.The present invention is that electric coal several hundred million is saved to 1,000,000,000 tons of youngsters in the whole nation every year.The present invention comes to this and has solved national electric coal deficiency, lacks the difficulty of peak load.Pilosity of the present invention water power reduced significantly electrical network hydroelectric plant dam site for many years all the generating of river rising in Ningxia and flowing into central Shaanxi stream half abandon water half abandon the water yield, improved the water resources capacity factor.The present invention has overcome existing technology electrical network peak regulation every day coal and has burnt in the same old way, and water is abandoned in the same old way, and the user is short of electricity in the same old way, and nationwide integrated power grid is the deficiency of short of electricity coal in the same old way.
Example five: certain water-saving Denso machine 3,290,000 kw, the present invention 5 years offer high prices for local water power by 0.08 hundred million kw.h/, ten thousand kw and come to be peak load regulation network, and electrical network water power annual multiple 2000 is utilized hour, ask the annual rate for incorporation into the power network of five annuals?
Hundred million yuan of 3,290,000 kw * 0.08 hundred million kw.h/, ten thousand kw=26.32, hundred million kw.h * 1.50 yuan/kw.h=39.48
3,290,000 kw * 2000 utilize hour=hundred million yuan of 65.8 hundred million kw.h * 0.10 yuan/kw.h=6.58
1 year: (39.48 hundred million yuan+6.58 hundred million yuan) ÷ (26.32+65.8)=(46.06 hundred million yuan-2,000,000,000 yuan) ÷ 92.12 hundred million kw.h=0.28 unit/kw.h
Subtracting 2,000,000,000 yuan in the formula is exactly not put into rate for incorporation into the power network to 2,000,000,000 yuan earlier, and the 4th puts into average electricity price again.
39.48 3500 yuan/kw of hundred million yuan of ÷ * 4000 utilizes hour=45.12 hundred million kw.h
45.12 hundred million yuan of hundred million kw.h * 0.05 yuan/kw.h=2.26
2 years: (39.48 hundred million yuan+6.58 hundred million yuan+2.26 hundred million yuan) ÷ (26.32+65.8+45.12)=0.35 yuan/kw.h
3 years: (39.48 hundred million yuan+6.58 hundred million yuan+2.26 hundred million yuan * 2) ÷ (26.32+65.8+45.12 * 2)=0.28 yuan/kw.h
4 years: (hundred million yuan of 39.48 hundred million yuan+6.58 hundred million yuan+2.26 hundred million yuan * 3+10) ÷ (26.32+65.8+45.12 * 3)=0.28 yuan/kw.h
Go into electricity price on average owing to put in 2,000,000,000 yuan for the first time 1,000,000,000 yuan in the formula.
5 years: (hundred million yuan of 39.48 hundred million yuan+6.58 hundred million yuan+2.26 hundred million yuan * 4+10) ÷ (26.32+65.8+45.12 * 4)=0.24 yuan/kw.h
It is average to put into electricity price to 1,000,000,000 yuan that owed in 1 year in the formula.
(0.28+0.35+0.28+0.28+0.24) ÷ 5=0.29 unit/kw.h
Answer: rate for incorporation into the power network was 0.28 yuan/kw.h in 1 year, deduct 2,000,000,000 yuan the 4th, the 5th year in the formula and refill, and 1 year 0.35 yuan/kw.h, third and fourth year is 0.28 yuan/kw.h, the 5th year is 0.24 yuan/kw.h online.In this example, electrical network 5,000,000,000 kw.h electric weight do not come average high price electric weight, and other is identical with example one.This example five annual rate for incorporation into the power network are 0.29 yuan/kw.h, and one five annual rate for incorporation into the power network of example is 0.262 yuan/kw.h.The present invention wherein contained to 19.74 hundred million yuan of local water power peak purchase expenses for electrical network and local water power increase income 4,600,000,000 yuan in 1 year, and 1 year is 48.32 hundred million yuan (19.74 hundred million yuan) ... the 5th year is 55.1 hundred million yuan (19.74 hundred million yuan).
