Description

Technical Field

[0001] The invention relates to a tidal flat stable power generation control system, belonging to the technical field of power supply. Background Art

[0002] With the rapid development of my country's new energy industry, tidal flat photovoltaics, as an emerging energy utilization method, is receiving increasing attention. Tidal flat photovoltaics refers to the installation of solar photovoltaic power generation systems in tidal flat areas, making full use of coastal tidal flat resources and realizing large-scale development of clean energy. Tidal flat photovoltaics include piles, which stand in the coastal tidal flats and have photovoltaic modules fixed on top. The piles receive sunlight through the photovoltaic modules and then convert it into direct current.

[0003] The direct current generated by the tidal flat photovoltaic module is converted into alternating current through inverter, and then boosted by the transformer, converted into high voltage and incorporated into the municipal power grid for external transmission. The power generation of the tidal flat photovoltaic module is often affected by the light intensity of the tidal flat. The AC voltage generated by the inverter fluctuates greatly. After being boosted by the transformer, the voltage fluctuation will be amplified. When it is incorporated into the municipal network, it will produce large voltage fluctuations. In addition, since the pile body stands in the seaside mudflat, the tidal effect of the sea water causes the mud and sand carried by the tide to easily accumulate around the pile body, forming a mud and sand wall, which not only hinders the flow of the tide, but also changes the direction of the water flow, aggravates the scouring of the pile body, and affects the fixation of the pile body and the power generation stability of the photovoltaic module. For this reason, some technicians in this field have developed a tidal flat stable power generation control system to overcome the problems in the above-mentioned background technology.

[0025] The voltage stabilizing structure also includes chip U1, which is an integrated operational amplifier. The model of chip U1 is LM358P.

[0027] Pin 1 of the chip U2 is connected to one end of the resistor R11, and the other end of the resistor R11 is connected to pin 1 of the chip U5. The chip U5 is an optocoupler, and the model of the chip U5 is TLP521. Pin 2 of the chip U5 is connected to the ground wire, and pin 3 of the chip U5 is connected to the power supply +24V. Pin 4 of the chip U5 is connected to the positive pole of the solid-state relay K2 coil, and the negative pole of the solid-state relay K2 coil is connected to the ground wire.

[0028] Pin 8 of the chip U2 is connected to the power supply +3.3V, pin 4 of the chip U2 is connected to the ground line, pin 2 of the chip U2 is connected to one end of the resistor R9 and one end of the resistor R10, the other end of the resistor R9 is connected to the power supply +48V, and the other end of the resistor R10 is connected to the ground line.

[0029] Pin 1 of the chip U3 is connected to one end of the resistor R8, and the other end of the resistor R8 is connected to pin 1 of the chip U6. The chip U6 is an optocoupler, and the model of the chip U6 is TLP521. Pin 2 of the chip U6 is connected to the ground wire, and pin 3 of the chip U6 is connected to the power supply +24V. Pin 4 of the chip U6 is connected to the positive pole of the solid-state relay K3 coil, and the negative pole of the solid-state relay K3 coil is connected to the ground wire.

[0030] Pin 8 of the chip U3 is connected to the power supply +3.3V, pin 4 of the chip U3 is connected to the ground wire, pin 2 of the chip U3 is connected to one end of the resistor R2 and one end of the resistor R3, the other end of the resistor R2 is connected to the power supply +48V, and the other end of the resistor R3 is connected to the ground wire.

[0031] The inverter AC power U comes from the inverter of the DC power emitted by the tidal flat photovoltaic panels, and then passes through the rectifier bridge composed of diodes D1 to D4 to integrate to form the DC positive pole V+, and flows into the ground through resistors R4, R5, R6 and R7. The voltage regulator diode D5 plays a role in voltage stabilization protection. The gate G of the thyristor VT collects the collector voltage of the transistor Q1. When the DC positive pole V+ voltage value is small, the voltage of the middle contact of the sliding rheostat R15 cannot break through the voltage regulator diode D6. The base of the transistor Q1 has no bias voltage and is not turned on. Therefore, the gate G of the thyristor VT is the same as the DC positive pole V+, the thyristor VT is turned on, and the common terminal COM1 of the solid-state relay K1 is connected to the inverter AC power U.

[0032] Because the voltage between the resistors R6 and R7 is collected at pin 3 of the chip U1, and the voltage between the resistors R12 and R13 is collected at pin 2 of the chip U1, when the voltage at pin 3 of the chip U1 is less than the voltage at pin 2 of the chip U1, the chip U1 is not conducting, that is, pin 1 of the chip U1 outputs a low level, the optocoupler chip U4 and the solid-state relay K1 are not conducting, the common terminal COM1 of the solid-state relay K1 is conducted with the normally closed point NC1 of the solid-state relay, and thus the common terminal COM1 of the solid-state relay K1 is conducted with the contact S1 in the transformer T1. At this time, the working turns of the input coil of the transformer T1 are the least. From the working principle of the transformer, it can be seen that the ratio of the input voltage to the number of turns of the input coil is equal to the ratio of the output voltage to the number of turns of the output coil. Since the number of turns of the output coil is fixed, the output voltage also needs to be a fixed value. When the input voltage is small, the working turns of the input coil are also the least.

[0033] When the values ​​of the inverter AC power U and the DC positive pole V+ increase, the voltage between the resistors R6 and R7 also increases. The voltage of the 3rd pin of the chip U1 is greater than the voltage of the 2nd pin of the chip U1. The chip U1 is turned on. The 1st pin of the chip U1 outputs a high level. The optocoupler chip U4 is turned on with the solid-state relay K1. The common terminal COM1 of the solid-state relay K1 is turned on with the normally open point NO1 of the solid-state relay K1. At this moment, the 2nd pin of the chip U2 collects the voltage between the resistors R9 and R10. The 3rd pin of the chip U2 collects the voltage between the resistors R5 and R6. The 3rd pin of the chip U2 is less than the 2nd pin of the chip U2. The chip U2 is not turned on, that is, the 1st pin of the chip U2 outputs a high level. A low level is output, the optocoupler chip U5 and the solid-state relay K2 are not conducting, the common terminal COM2 of the solid-state relay K2 is conducted with the normally closed point NC2 of the solid-state relay K2, and thus the common terminal COM1 of the solid-state relay K1 is conducted with the contact S2 in the transformer T1, and the working turns of the input coil of the transformer T1 increase. Therefore, through the working principle of the above voltage stabilization structure, according to the size of the inverter AC power U of the tidal flat photovoltaic module, the size of the working turns of the input coil of the transformer T1 is adjusted, and when the output coil of the transformer T1 is certain, the voltage value of the output terminal of the transformer T1 is stabilized, so that the tidal flat photovoltaic power generation is more stable and balanced when it is incorporated into the municipal power grid.

[0034] If the values ​​of the inverter AC power U and the DC positive pole V+ continue to increase, the voltage of the middle contact of the sliding rheostat R16 continues to increase. When the voltage of the middle contact of the sliding rheostat R16 increases to a certain value, the voltage of the middle contact of the sliding rheostat R15 can break down the voltage-stabilizing diode D6, the base of the transistor Q1 is electrically turned on, the gate G of the thyristor VT is turned on to the ground, and the thyristor VT is turned off. Therefore, the common terminal COM1 of the solid-state relay K1 is disconnected from the inverter AC power U, preventing the inverter AC power U and the DC positive pole V+ from being too large, exceeding the voltage setting value of the input terminal of the transformer T1, and causing damage to the transformer T1.

[0035] like Figure 3 and Figure 4 As shown, the sand-blocking structure includes a pile body 1, which stands on the mudflat. A photovoltaic component 2 is fixedly connected above the pile body 1, and a blocking component 3 is fixedly connected between the pile bodies 1. The blocking component 3 includes a blocking groove 4, which is tilted and arranged with one end of the blocking groove 4 open and the other end closed. The closed end of the blocking groove 4 faces upward, and the open end of the blocking groove 4 faces the seashore. A partition 5 is provided in the blocking groove 4, and the partitions 5 are evenly arranged on the inner wall surfaces on both sides of the blocking groove 4. A filter screen 8 is also provided at the lower end of the partition 5, and the filter screen 8 is fixed to the inner wall of the blocking groove 4.

[0036] A reciprocating cylinder 6 is also fixedly connected to the outer wall of the closed end of the blocking groove 4, and the end of the reciprocating cylinder 6 extends into the blocking groove 4. A cleaning plate 7 is fixedly connected to the end of the reciprocating cylinder 6, and the cleaning plate 7 is located between the bottom of the blocking groove 4 and the filter screen 8.

[0037] The open end of the blocking groove 4 is provided with a baffle 10, and the upper end of the baffle 10 is provided with a rotating shaft 9. The two ends of the rotating shaft 9 are located on the inner walls of the two sides of the blocking groove 4 and can rotate on the inner walls of the two sides of the blocking groove 4. A spring 11 is also connected between the baffle 10 and the partition 5. At ordinary times, under the action of the spring 11, the baffle 10 blocks the open end of the blocking groove 4. When the sea water rises and surges towards the mudflat, when the sea water passes through the blocking groove 4, the open end of the blocking groove 4 is blocked by the baffle 10 and cannot enter the blocking groove 4 from the baffle 10. The sea water bypasses the baffle 10 and enters the blocking groove 4 from the top of the blocking groove 4. It is washed upward along the blocking groove 4. After being blocked by the partition 5, the flow rate becomes slower and slower, and then passes through the filter screen 8 and falls into the blocking groove 4. When the sea water ebbs, the baffle 10 is opened by the pressure of the sea water above the blocking groove 4, and the opening of the lower end of the blocking groove 4 is opened, and the sea water above the blocking groove 4 flows out from the blocking groove 4. When the sea water rises and falls, it can prevent sea water and sediment from scouring the pile body 1.

[0038] The bottom of the blocking trough 4 is subjected to the tidal effect of seawater for a long time. The mud and sand on the bottom surface of the blocking trough 4 that cannot be carried away by the seawater adhere to the bottom surface of the blocking trough 4. At regular set time intervals, the reciprocating cylinder 6 retracts and contracts once. When the reciprocating cylinder 6 extends, it drives the cleaning plate 7 to move downward, pushing out the mud and sand attached to the bottom surface of the blocking trough 4.

Many modifications and variations will be apparent to those skilled in the art.
