Description
Technical field
The present invention relates to field of renewable energy more particularly to a kind of wind-force photo-thermal power generation equipment that can be used for peak load regulation network
And method.
Background technique
Traditional fossil energy power generation has had resulted in the environmental problems such as more serious air pollution, climate warming, acid rain,
Exhaustive exploitation can also accelerate fossil energy to exhaust, environmental issue and energy resource structure problem are increasingly taken seriously, due to renewable
The energy is widely distributed and minimum to environmental hazard, and renewable energy power generation becomes one kind of the unsustainable problem of conventional Power Generation Mode
Solution.In field of new energy generation, wind energy and solar energy are two kinds of more renewable and clean energy resources of current application.Wherein
Solar power generation is divided into photovoltaic power generation and photo-thermal power generation two ways again.Photovoltaic power generation reaches its maturity, commercial applications are more, photo-thermal
Power generation is then in starting demonstration phase.
In addition, current electric grid deposits problem both ways, first is that load distributes imbalance, electric load peak-valley difference at any time
Greatly, it is unstable to easily lead to operation of power networks；Second is that the grid-connected scale of new energy electric power is increasing, and the generally existing electricity of new energy electric power
The inferior problem of energy increases the unstable of operation of power networks such as wind-powered electricity generation, photovoltaic power generation, and the grid-connected consumption of new energy electric power is difficult.
Therefore, the balance that measures to regulate rush-hour traffic must be taken to guarantee electric system for electricity consumption in operation of power networks, while making to receive and dissolving new energy
The ability of source electric power is continuously improved.There is currently many peak regulation methods, in traditional peak regulation method, thermoelectricity peak regulation can discharge atmosphere dirt
Dye object causes environmental problem, and gas turbine unit peak regulation cost is higher, and hydroelectric peak has advantage but unit will more undertake
The base load of power grid, abandoning water peak regulation will cause very big waste；Novel peak regulation method mainly has batteries to store energy peak regulation, superconducting magnetic
Energy storage peak shaving, compressed-air energy storage peak regulation etc., these peak regulation method cardinal principles are by various energy storage modes by the low storage of electric paddy
Store away, then released in the peak of power consumption period, be at conceptual phase substantially, though have certain application each there is also
Some problems, main problem first is that cost is higher, cost decline is difficult.
Although currently, wind-power electricity generation and photovoltaic power generation technically reach its maturity, commercial applications are also continuously improved, cost
It constantly reduces, alleviates the environmental problems such as air pollution, climate warming, but the selection of wind power plant is limited by wind-resources, wind
The state and power output size of power power generation are determined by wind speed size, so that wind-power electricity generation has energy density low, unstable, uncontrollable
Etc. disadvantages；And photovoltaic power generation must have energy-storage system, that there are cycle lives is short for more common lead-acid accumulator energy-storage system,
The disadvantages of power density is low, maintenance is big, increases cost of electricity-generating, while sunlight is equally existed by inside even from weather is larger
Unstable disadvantage.In comparison, the photo-thermal power generation in starting demonstration phase, it is close with traditional thermal power generation principle, though
The problem for so also having solar illuminating unstable, but it is equipped with heat reservoir, first is that can satisfy night power generation requirements, two
It is that can provide buffering for solar energy unstability, so that power generation process is more stable, the electric energy of sending has higher quality, with fire
Electric electric power quality is suitable, and tool has great advantage.In addition, photo-thermal power generation power station Turbo-generator Set can be using similar thermoelectricity peak regulation
Off-Design Operation Mode, such as underload peak regulation, start and stop daily start stop, few zero load peak regulation of steam, slow-speed of revolution rotation are hot standby
With peak regulation etc., to cooperate peak load regulation network, although there are some problems, such as the expansion and swollen poor, unit thermal deformation, steam turbine of unit
Exhaust stage blade working condition etc., but the pollutants such as carbon dioxide, dust, lime-ash are not discharged, clean and environmental protection, meanwhile, the storage of outfit
The principle that similar various novel peak regulation methods can be used in hot systems carrys out peak regulation, trough-electricity is stored in the form of heat, then
Heat is used to generate electricity in the peak of power consumption period, or is used for heat supply, such as carries out heat supply to factory, residential block, industrial equipment, is reached
To peak regulation purpose.
Although wind-power electricity generation has some weakness, new energy electric power apoplexy electricity installation amount and grid-connected amount are the largest, so
And abandonment amount is also the largest, the northwestward and northeast that especially wind-resources are abundant but power grid receiving ability is weaker.Northwestward wind
Resourceful, light resource is also enriched, early stage wind-powered electricity generation photovoltaic complementation power station, and it is with strong complementarity with wind energy resources to be utilized solar energy, and one
Determine to compensate for the defect of wind-power electricity generation and photovoltaic power generation autonomous system in resource in degree, while two kinds of systems are in energy-storage system
Being with inversion system possible general, so that this reduction of system synthesis, very applicable and separate bulk power grid, meagrely-populated, traffic are not
Just outlying district, but can not still solve the problems, such as power quality.And wind-powered electricity generation and photothermal complementary power station, then it can possess wind-powered electricity generation light
The advantage in complementary power station is lied prostrate, meanwhile, it is stored the low-quality electricity that abandonment can be issued, and abandonment amount is reduced, with photo-thermal electricity
The high-quality electricity mixing output stood improves power station power quality, and the peak regulating function of photo-thermal power station can also help peak load regulation network, mention
The digestion capability of high grid stability and power grid to new energy electric power.
