Embodiment
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with example, the utility model is specifically described.Should be appreciated that following word only in order to describe one or more concrete execution modes of the present utility model, considered critical is not carried out to the protection range that the utility model is specifically asked.
The technical scheme that the utility model is taked as shown in Figure 1, a kind of wind and solar hybrid generating system, it comprises wind turbine generator for load supplying and solar energy thermal-power-generating unit, and detects in real time the power output of wind turbine generator and solar energy thermal-power-generating unit and regulate and control the modulator of wind turbine generator and solar energy thermal-power-generating operating states of the units according to the result detected in real time respectively.
The present invention utilizes power coordination control method to adopt hierarchical control architecture, and wind and solar hybrid generating system is divided into two-stage, and higher level's decision package is power coordination controller, and subordinate's decision package is two subsystems.
Modulator comprises and carries out each transducer of examinations to wind speed, temperature, direct solar radiation illumination, solar energy heat-collection field import and export temperature and heat storage can energy and each transducer is carried out to the data processing unit of data processing, data processing unit, according to the wind speed of the current collection of each transducer, temperature, sun direct projection irradiance and the data such as solar energy heat-collection field out temperature and heat storage can energy, calculates the real-time power output of wind power generation and photo-thermal power generation.The power output of wind turbine generator calculates by Wind resource change relation, photo-thermal power generation is relatively complicated, should consider the heat-collecting capacity under current light condition, considers the heat accumulation energy of heat storage can again, be multiplied by the generating efficiency of steam turbine again, the power output of photo-thermal power generation.
As shown in Figure 2, wind generator system is a complication system to the Poewr control method of wind turbine generator, and non-linear, strong jamming, multivariable, model are uncertain, and its work wind speed range is wide, and moment of inertia is large, and coefficient damping ratio is unstable, there is close coupling.The power of PI type Fuzzy adaptive control algorithm to variable pitch blower fan is adopted to control, fuzzy control is utilized not need the mathematical models of controlled device, not by the impact of non-linear factor with the parameter fluctuation of controlled device is had to the on-line tuning that the advantages such as stronger robustness realize controller PI parameter.
The control of photo-thermal power generation unit is formed primarily of power station model and MPC controller, and need the outlet temperature controlling heat collector, conduction oil volume flow rate, the control of power output is realized by MPC controller, as shown in Figure 3.And turbo generator also has controllability, the effective control to power output can be realized.
