Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power auxiliary equipment, in particular to an intelligent high-voltage reactive power compensation system based on a converter. BACKGROUND

[0002] With the rapid development of social economy, the demand for energy is also increasing, among which the power generation equipment based on water power, wind power and solar energy is widely used due to energy saving and environmental protection. The current water turbine generally needs to build a dam to generate electricity, which has the disadvantages of large investment and high power generation cost.

[0003] In the existing technology, there is also a simple water power generation device (hereinafter referred to as a floating water turbine), which mainly includes a guide frame, a floating box and a water turbine. The guide frame is directly inserted into the river, and the floating box moves up and down according to the water level of the river to ensure that the paddle of the water turbine installed thereon is always located below the water surface to be impacted to drive the generator to generate electricity. Although the floating water turbine has the advantages of simple structure, convenient operation and low investment cost, due to the limitation of the structure, the floating box will block the foreign matters such as branches, leaves and weeds above the water surface of the river, that is, the foreign matters are easy to block the front end of the floating box, and then the paddle (located at the side end of the floating box) of the floating water turbine will be blocked by the foreign matters, which will slow down the rotation speed or even not rotate to generate electricity, which has an adverse effect on its effective application. Under normal circumstances, special maintenance personnel need to check the working condition of the floating water turbine every certain time, and clean it in time when the foreign matter is blocked to ensure that the floating water turbine is in normal power generation state. The above mode not only brings inconvenience to the workers, but also increases the unnecessary labor cost of the relevant management party. Therefore, it is particularly necessary to provide a high-voltage reactive power compensation device body based on a converter, which can effectively utilize water power generation and reduce the workload of workers and labor cost of relevant parties.

[0017] Figure 1 、 2As shown, the power input end of the high-voltage reactive compensation device body A2 and the AC 380V power supply are connected through a wire, the power output end of the water turbine generator M and the signal power input end of the high-voltage reactive compensation device body A2 are connected through a wire, and the power output end of the high-voltage reactive compensation device body A2 and the power input end of the load FZ are connected through a wire; the power input end 1 and the 2 pin of the voltage stabilizing module A1 and one of the phase line and the zero line (220V) of the water turbine generator M are respectively connected through a wire, the positive electrode of the signal input end diode VD1 of the prompt circuit and one of the phase line of the water turbine generator M are connected through a wire, the positive electrode power input end of the power input end relay K of the prompt circuit and the emitter of the NPN triode Q1, the 1 and 2 pin of the time control switch A6 of the power input end of the control circuit, the positive electrode power input end of the power input end relay K3 of the output circuit and the emitter of the NPN triode Q2 and the power output end 3 and 4 pin of the voltage stabilizing module A1 are respectively connected through a wire; the signal output end 9 pin of the time relay module A3 of the output circuit and the negative electrode of the signal input end diode VD of the control circuit are connected through a wire, the power output end 3 and 4 pin of the time control switch A5 and A4 of the control circuit and the positive and negative and negative positive two power input ends of the motor speed reduction mechanism M3 are respectively connected through a wire.

[0018] Figure 1 , 2As shown, the application is based on the high-voltage reactive power compensation device body A2 with a converter, in application, the electric energy generated by the hydraulic generator M is stored in the super capacitor inside the high-voltage reactive power compensation device body A2, when the power supply at the load end is unstable, the super capacitor will output power supply to the load end FZ through the power supply converter in the high-voltage reactive power compensation device body A2 to stabilize the power supply, and since the hydraulic generator M does not use fossil energy, etc., the purpose of energy saving and environmental protection can be achieved. The 220V alternating power supply output by one phase line and zero line of the hydraulic generator M enters the power input end of the voltage stabilizing module A1, and the power output end of the voltage stabilizing module A1 outputs stable DC 12V power supply to the power input end of the prompt circuit, control circuit and output circuit, so that the above-mentioned circuits are in power-on working state. In the application, the floating box 1 will move up and down along the fixed rod 2 through the guide pipe 101 under the influence of the change of the river water level, so that more than half of the two paddles 6 are always located above the water surface and are impacted by the water flow to rotate, and then the rotating shaft of the hydraulic generator M rotates to generate electric energy and enters the super capacitor storage. After the prompt circuit is powered on, if the water current generator M normally outputs power supply, then the power supply output by one phase line will enter the base of NPN triode Q1 through half-wave rectification of diode VD1, voltage reduction and current limiting of adjustable resistor RP, so that NPN triode Q1 is turned on and the low level is output to the negative power input end of relay K, and the relay K is powered on to attract the open circuit between the control power input end and the normally closed contact end, so that the 3-pin of SMS module A7 does not input low level signal, and it does not send SMS. When the water current generator M does not generate electricity due to various reasons (including damage, extreme situation of weeds in water winding the paddle, non-rotation of the paddle leading to no electricity generation or low electricity generation of the hydraulic generator), then one phase line no longer outputs power supply to the base of NPN triode Q1 (or the voltage is lower than 0.7V), so that NPN triode Q1 is cut off, and the relay K is not powered on to close the control power input end and the normally closed contact end, so that the 3-pin of SMS module A7 is input with low level signal, and under the action of the internal circuit of SMS module A7, SMS module A7 will send a pre-stored SMS, and the related personnel connected with SMS module A7 receive the SMS by mobile phone to know that the hydraulic generator M does not generate electricity in the first time, and timely go to the scene for targeted treatment.

[0019] Figure 1 、 2As shown, if the water flow through the floating box 1 is unobstructed, that is, there is no foreign matter in front of the floating box 1 and the paddle 6, the micro DC generator M1 blade is rotated by the impact of the water flow, and the voltage generated is relatively high. The positive electrode of the DC power supply is reduced and limited through the resistor R3, and the base of the NPN triode Q2 is higher than 0.7V, so the NPN triode Q2 is turned on and the low level output of the collector is input into the negative electrode power supply input terminal of the relay K3. The relay K3 is energized to open the control power supply input terminal and the normally closed contact terminal, so that the 3 pin of the time relay module A3 does not input high level signal and the 9 pin has no output. When the water flow through the floating box 1 is not unobstructed, that is, there is foreign matter in front of the floating box 1 and the paddle 6, the voltage generated by the micro DC generator M1 is relatively low, the base of the NPN triode Q2 is lower than 0.7V, and the NPN triode Q2 is cut off, so that the collector no longer outputs low level to the negative electrode power supply input terminal of the relay K3. The relay K3 is de-energized, and the control power supply input terminal and the normally closed contact terminal are closed, so that the positive electrode of the 12V power supply is input into the 3 pin of the time relay module A3 through the positive electrode power supply input terminal and the normally closed contact terminal of the relay K3. The time relay module A3 outputs a certain time power (such as 5 minutes) into the positive electrode power supply input terminal of the time control switch A5 and A4 under the output power time of the 9 pin in the internal circuit and the technical personnel setting, so that the time control switch A5 and A4 are energized and work. The time control switch A6 is energized and works under the output power time of the 3 and 4 pins in the internal circuit and the technical personnel setting, and outputs a certain time power through the unidirectional conduction of the diode VD into the positive electrode power supply input terminal of the time control switch A5 and A4 every certain time (such as 5 minutes every 4 hours), so that the time control switch A5 and A4 are energized and work. The time control switch A5 is energized and works for 5 minutes, and outputs a certain time power into the positive and negative electrode power supply input terminal of the motor speed reduction mechanism M3 under the output power time of the 3 and 4 pins in the internal circuit and the technical personnel setting, and then stops outputting power (such as outputting 1 minute power first, and then stopping outputting power). The time control switch A4 is energized and works for 5 minutes, and outputs a certain time power into the negative and positive electrode power supply input terminal of the motor speed reduction mechanism M3 at a certain time interval under the output power time of the 3 and 4 pins in the internal circuit and the technical personnel setting, and then stops outputting power (such as outputting 1 minute power every 4 minutes, and then stopping outputting power). The positive and negative electrodes of the motor speed reduction mechanism M3 are energized and work for 1 minute, and the power output shaft rotates clockwise to wind the steel wire rope 10 through the winding wheel 9, so that the distance between the steel wire rope 10 and the upper end of the floating box 1 gradually decreases, and the upper end of the floating box 1 rises to contact the lower end of the fixed shell 7. Because the lower end of the floating box 1 is pulled away from the water surface at this moment, the dry branches, leaves and aquatic plants originally blocked in front of the floating box 1 and the paddle 6 will fall down and be impacted by the water flow to the downstream, so as not to block the subsequent floating box.Within 1 minute of the negative and positive poles of the motor reduction mechanism M3 being energized, its power output shaft will rotate counterclockwise to unwind the thin steel wire rope 10 through the winding wheel. This will gradually increase the distance between the steel wire rope 10 and the upper end of the pontoon 1, and the lower end of the pontoon 1 will drop to touch the water surface. Since the pontoon only contacts the water surface for about 40 seconds, the steel wire rope is unwound (with a length margin) for the remaining 20 seconds to ensure that the pontoon has enough room to float up and down when the water level changes. Through the joint action of all the above-mentioned mechanisms and circuits, in the present invention, especially under the joint action of the water flow detection mechanism and the control circuit, the height of the pontoon can be automatically raised at regular intervals and when the water flow slows down before flowing through the pontoon, so that various branches, weeds, etc. blocking the front end of the pontoon and the blades can automatically fall into the water and be washed downstream, thereby clearing foreign objects above the water surface of the river in front of the pontoon and the blades. In extreme cases, when the blades do not rotate for various reasons, the hydroelectric generator does not generate electricity, or the power generation capacity drops below a certain level, the prompt circuit can promptly prompt relevant personnel to perform maintenance via text message, thereby ensuring that the blades of the hydroelectric generator are effectively impacted by the water flow and generate electricity; the present invention correspondingly reduces the number of inspections and maintenance by staff, brings convenience to staff, and reduces the labor costs of related parties. Figure 2In the embodiment, the SMS module A7 is a SMS module of model GSM 800, the SMS module A7 has two power input terminals 1 and 2 pins, signal input ports 3-8 pins, after each signal input port inputs a low level signal, the SMS module A7 will send a SMS through a wireless mobile network, the SMS module A7 stores a SMS, in the embodiment, the SMS is "stop generating electricity", after the signal input port 3 pin of the SMS module A7 is inputted with a low level signal, the SMS module A7 can send the SMS; the time control switches A6, A5 and A4 are microcomputer time control switch products of model KG316T, the time control switch has seven keys, and has two power input terminals 1 and 2 pins, two power output terminals 3 and 4 pins, a user can set the interval time of the power output of the two power output terminals and the time of each power output by pressing the seven keys; the resistance R3 has a resistance value of 1K; the adjustable resistance RP is of model 10M (in the embodiment, the adjustable resistance RP is adjusted to about 4.8M); the NPN triodes Q1 and Q2 are of model 9013; the diodes VD and VD1 are of model 1N4007; the relays K3 and K are of model DC12V; the time relay module A3 is of model YYC-2S, the time relay module A3 has two power input terminals 1 and 2 pins, two trigger signal input terminals 3 and 4 pins, a setting key 5 pin, an emergency stop key 6 pin, a time increase key 7 pin, a time decrease key 8 pin, and a normally open power output terminal 9 pin, after the positive and negative power input terminals of the time control switch A5 are powered, a user sets the keys, and then operates the time increase key and the time decrease key, the normally open power output terminal can output the positive power in the required time period, after the set time period, the normally open power output terminal stops outputting the power, after the time is set and the two trigger signal input terminals are inputted with trigger power signals, the time relay module product starts timing for the set time.
