In conventional design, the main body generating of hybrid exploitation generally only adopts a set of long tunnel generating system by piloting water, and full installed capacity generates electricity, equivalent annual utilization hours is generally little.But when the engineering such as diversion tunnel and surge shaft difficulty and investment are obviously larger, main body generating concentrates on long diversion downstream may produce considerable influence to the exploitation in power station and economy, have readjust installation lay thinking necessity and may.
On the other hand; for preserve the ecological environment and dam downstream river other use water requirement; hybrid exploitation also lets out certain base lotus flow under Xu Ba district; this base lotus flow is relatively also not very too large at present; but may develop from later; particularly in great rivers, this base lotus flow will require obvious increase.From taking into account long-range environmental requirement, beyond former base lotus flow, increasing dam district generating system by piloting water, also can reserve certain development space to environmental protective measure.
Summary of the invention
The object of the present invention is to provide a kind of method that large discharge mixed type hydropower station Divisional is installed, by setting up dam district generating system by piloting water, at the water yield richer period multiple electricity, reduce the scale of long tunnel diversion system, corresponding minimizing engineering difficulty, investment etc., do not affect again long generating system by piloting water at average water and the power benefit in dry season.
Technical scheme of the present invention is such: set up a set of generating system by piloting water at Ba Qu, combines with tunnel generating system by piloting water; At the water yield richer period multiple electricity, reduce the scale of long tunnel diversion system, do not affect again long generating system by piloting water at average water and the power benefit in dry season.Further, when distant view wet season electricity and electricity price higher, and when additional investment benefit economy is feasible, environmental impact assessment is feasible, the flow also this can being set up Ba Qu generating builds the water diversion of long tunnel diversion and power installation as the second phase.
Compared with prior art, the present invention is aobvious decreases original hydro-power station engineering difficulty and investment largely, improves the economic benefit of engineering, is conducive to the exploitation promoting power station; Simultaneously also for measure space has been reserved in later ecological environmental protection development.
Technique effect of the present invention is: to set up Ba Qu (factory building and) generating system by piloting water, reduce the installation scale of tunnel water channeling type power generation part, improve tunnel utilization rate, significantly reduce former generating diversion system scale and investment, improve power station economy and technological adaptability.The Ba Qu that sets up generates electricity diversion system, and after also can be, under ecological environmental protection or dam, section water will be sought development, and provides larger measure space.The dam district generating system by piloting water set up is a kind of important means improving power station initial stage power benefit, reduce engineering funds input.Hybrid exploitation, the Qi Ba district generating system by piloting water duration is short, and can generate electricity early than tunnel generating system by piloting water, initial stage power benefit is larger.The dam district generating system by piloting water set up can be used as a kind of means reducing the engineering such as diversion tunnel, surge shaft difficulty.Under given conditions, the dam district generating system by piloting water also this can be able to set up is not implemented, or distant view replaces the second phase of the project of growth tunnel generating system by piloting water.
Accompanying drawing explanation

(1) engineering specifications feature: the engineering difficulty of long tunnel diversion system is large or investment accounting is large, the dam district generating system by piloting water investment of setting up is relatively little;
(2) discharge of river feature (river is all like this): the larger then frequency of occurrences of (more than ordinary flow) flow is lower, after reducing long diversion system scale, oepration at full load equivalence annual utilization hours improves, and generated energy reduces not obvious;
(3) electricity market feature: the electricity in flood season that water power enriches area is generally more, and has more than needed, also may with occur that flood season rate for incorporation into the power network is low; Or abundance of water generated output and capacity are large, exceed the installation of part and send uneconomical; After reducing long diversion scope, economic benefits of power generating reduces not obvious;
(4) generate electricity feature in advance: the dam district generating system by piloting water set up, and its power generation time normal comparatively the long diversion tunnel part early, is conducive to early income, minimizing investment, facilitates capital collection;
(5) under ecological environment or dam, the distant view of section water requires to improve, reserved measure space.
(6) operation and benefit guarantee: under the base flow sluicing conditions such as satisfied ecology, when ordinary flow and low discharge, preferentially generate electricity with the long tunnel generating system by piloting water that productive head is larger, power station whole economic efficiency can be ensured; When flow is bigger, increase the generating system by piloting water generating of dam district, Appropriate application abundance of water resource, improves power benefit.
