Description
Technical field
The invention patent relates to be a kind of technical solution that family formula photovoltaic heating special equipment is constituted.The family formula photovoltaic is adopted
Warm special equipment has two kinds of photovoltaic outputs as needed: 1) when needing heating, direct DC/DC output photovoltaic direct current power is used
It powers in heating electric heater；2) when not needing heating, the photovoltaic electric power DC/AC output grid-connected electric power of 50Hz sine wave (is equal to
Normal gird-connected inverter).
Background technique
It is well known that winter heating mostly burns coal (or stalk, timber etc.) using scattered in China's the vast rural areas.It is
Cause one of the important origin cause of formation of atmosphere pollution and winter haze.Currently, clean energy resource heating is carried out energetically by country, and solar energy is to work as
Modern universally acknowledged cleaning new energy most with prospects, northern area sunshine condition is generally preferable, to carry out northern country
Carry out photovoltaic heating and provide bright prospects in area.
The distributed photovoltaic application that facts have proved on-site elimination is the most correct method of photovoltaic application development.Therefore, adhere to
One kind that the photovoltaic heating of on-site elimination method will gradually develop into northern country regional " clean energy resource heating " is main
Form.
Summary of the invention
The invention patent is a kind of special equipment composition technical solution applied in photovoltaic heating system.The special equipment
The mode of special equipment output photovoltaic electric power can be controlled according to heating demand and photovoltaic power generation situation, direct current photovoltaic is used for heating
Electric power supply exchanges output with photovoltaic grid-connected inversion.
The equipment of use constitutes technical solution: being controlled by Boost voltage regulator circuit (1), photovoltaic maximal power tracing MPPT
(2), output mode control (3), PWM inverter module (4) composition.
Photovoltaic heating special equipment operating mode is: photovoltaic DC input is maximum by Boost voltage regulator circuit (1) and photovoltaic
Power tracking MPPT controls (2), and the maximum dc power that photovoltaic DC electric power is adjusted to burning voltage is exported；Again by output mould
Formula controls (3) and whether is used for heating according to the photovoltaic electric power, determines to be by the direct direct current output of Ka by photovoltaic electric power to impedance
The power supply of class Electric heater；Or the 220VAC(8KW that PWM inverter module (4) output meets the grid-connected requirement of power grid is connected to by Kb
Scale and following)/380VAC(10KW scale or more) three-phase sine-wave exchange output.
Technical points are: output mode control (3) is subjected to external control signal and determines special equipment output electricity
Power type is that direct current is used for heating for electric heating or inversion grid connection AC power.Dedicated set is determined by output mode control (3)
Direct current or parallel network reverse AC power when standby output.
Detailed description of the invention
The family Fig. 1 photovoltaic heating system block diagram and special equipment constitute technical solution.
Specific embodiment
Step 1: photovoltaic DC input is stablized photovoltaic electric power in a suitable voltage by Boost voltage regulator circuit (1)
In range (300~600VDC, according to inversion grid connection needs).
Step 2: realize that instant photovoltaic generation power is maximum by photovoltaic maximal power tracing MPPT control (2).
Step 3: output mode controls (3) according to external control signal, and if desired the photovoltaic electric power is used for heating, then will
The photovoltaic electric power (is powered) by the direct direct current output of Ka to impedance type heating electric appliance or electric boiler；
Step 4: if the photovoltaic electric power is not used in heating, it is inverse by Kb connection PWM that output mode controls (3) control photovoltaic electric power
Become module (4), photovoltaic electric power inversion output met to the 220VAC/380VAC(three-phase of the grid-connected requirement of power grid) sine wave.
When system has photovoltaic power generation, special equipment cycle operation in cycles in this way.
