Technical Field

[0001] The invention relates to an intelligent power distribution system, belonging to the technical field of power distribution. Background Art

[0002] With the rapid development of modern society, the demand for electricity is increasing, and higher requirements are placed on the reliability and stability of power supply. Traditional power distribution systems often have many shortcomings during operation, such as the monitoring of power parameters is not accurate and timely enough, it is difficult to quickly warn and locate faults, there are limitations in the rationality and flexibility of power distribution, it is impossible to effectively adapt to the dynamic changes in the needs of different loads, and there is still a lot of room for improvement in energy efficiency. These problems may not only lead to power supply interruptions and affect the normal order of production and life, but also cause energy waste and increase in operating costs. Therefore, the development of a new type of intelligent power distribution system is of great practical significance. Summary of the invention

[0003] The purpose of the present invention is to provide an intelligent power distribution system to solve the above problems existing in the existing power distribution system and to improve the intelligence level, reliability, energy utilization efficiency and adaptability to different load demands of the power distribution system.

[0004] An intelligent power distribution system of the present invention comprises an intelligent monitoring unit, a central control unit, an intelligent protection unit, a power distribution unit and a human-computer interaction unit; wherein the intelligent monitoring unit comprises a power parameter acquisition module, an environmental monitoring module and a data transmission module; the central control unit comprises a data processing and analysis module and a control strategy generation module; the intelligent monitoring unit continuously acquires power parameters and environmental parameters, and transmits the data to the central control unit through the data transmission module, and the data processing and analysis module of the central control unit processes and analyzes the data in real time; the intelligent protection unit monitors the operating status of the power distribution system in real time, and once a fault such as overcurrent, overvoltage, leakage, etc. is detected, the protection action is immediately started, the faulty line or equipment is cut off, and a fault signal is sent to the central control unit; the power distribution unit receives instructions issued by the central control unit to perform power distribution operations; the human-computer interaction unit is used for data management through human-computer interaction processing.

[0005] In one embodiment of the present invention, the power parameter acquisition module is equipped with a high-precision sensor, which can collect key power parameters such as voltage, current, power factor, active power, reactive power, etc. in the distribution line in real time. For example, a Hall effect sensor is used to measure the current, which has the advantages of high precision, wide range, fast response speed, etc., and can accurately obtain the magnitude and change of the current. The voltage sensor uses an isolated voltage transformer to ensure safe and reliable acquisition of voltage signals under high voltage environments. The collected signal is filtered, amplified, and processed by a signal conditioning circuit to improve the quality of the signal and facilitate subsequent analog-to-digital conversion and data analysis.

[0006] In one embodiment of the present invention, the environmental monitoring module is used to monitor the temperature, humidity, smoke and other parameters of the environment in which the power distribution equipment is located. The temperature sensor adopts a thermistor sensor, which can quickly respond to changes in the ambient temperature. When the temperature exceeds the set threshold, it will issue a warning signal in time to prevent the power distribution equipment from being damaged due to overheating. The humidity sensor can adopt a capacitive humidity sensor to accurately measure the ambient humidity and avoid problems such as the degradation of electrical insulation performance due to excessive humidity. The smoke sensor can use a photoelectric smoke sensor. Once smoke is detected, an alarm is immediately triggered to indicate that there may be a fire hazard, thereby ensuring the safe operation of the power distribution system.

[0007] In one embodiment of the present invention, the data transmission module transmits the collected power parameters and environmental parameters to the central control unit through a combination of wired (such as Ethernet, RS485, etc.) and wireless (such as Wi-Fi, Bluetooth, 4G / 5G, etc.). For communication between devices with high real-time requirements and short distances, high-speed Ethernet connection is preferred; for some monitoring points that are more dispersed and inconvenient to wire, wireless communication is used to ensure that data can be transmitted stably and quickly, so as to achieve comprehensive monitoring and data sharing of the entire power distribution system.

[0008] In one embodiment of the present invention, after the data processing and analysis module receives various data from the intelligent monitoring unit, the module uses advanced algorithms to process and analyze the data. For example, the fast Fourier transform (FFT) algorithm is used to perform spectrum analysis on the collected voltage and current signals to detect whether there is harmonic pollution and calculate the harmonic content. By analyzing historical data, a power parameter change trend model is established to predict changes in power demand and provide a basis for reasonable power distribution. At the same time, environmental parameters are monitored in real time. When environmental parameters are abnormal, corresponding protection measures or alarm mechanisms are activated according to preset rules. For example, when the temperature is too high, the heat dissipation device (such as a fan, air conditioner, etc.) is automatically started, and an alarm message is sent to the operation and maintenance personnel.

[0009] In one embodiment of the present invention, the control strategy generation module generates a corresponding control strategy based on the results of data processing and analysis. For example, during the peak period of power load, by optimizing the power distribution algorithm, the power supply of important loads is prioritized, and appropriate power restriction or peak-shifting power consumption control is performed on non-critical loads. For the case of low power factor, a reactive power compensation control instruction is generated to control the reactive power compensation device to put in or remove the capacitor bank to improve the power factor and reduce reactive power loss.

[0010] In addition, the module also has adaptive control capabilities, which can automatically adjust the control strategy according to the operating status of the distribution system and changes in the external environment to ensure that the distribution system is always in the best operating state.

[0011] In one embodiment of the present invention, the intelligent protection unit includes an overcurrent protection module, an overvoltage protection module and a leakage protection module.

[0012] The overcurrent protection module monitors the current in the distribution line in real time, and quickly initiates the protection action when the current exceeds the preset overcurrent protection threshold. By combining fast fuses and intelligent electronic trips, the fast fuses can instantly cut off large current faults and play a role in short-circuit protection; the intelligent electronic trip can achieve overload protection and selective protection according to the current size and duration, avoiding power outages in the entire distribution system due to local faults.

[0013] The overvoltage protection module monitors the voltage value. When the voltage exceeds the set upper limit, the voltage is limited or discharged through devices such as voltage regulators or lightning arresters to protect the power distribution equipment from the impact of excessive voltage. For example, a metal oxide lightning arrester is used, which has good nonlinear volt-ampere characteristics and presents a high resistance state under normal voltage. When the voltage is too high, the resistance decreases rapidly, and the overvoltage energy is introduced into the ground, ensuring the safe and stable operation of the power distribution system.

[0014] The leakage protection module detects the leakage current in the distribution line. Once the leakage current exceeds the safety threshold, the power supply is immediately cut off to prevent electric shock accidents. The residual current operated protector (RCD) is used, which determines whether there is leakage by detecting the vector sum of the live and neutral currents. It has the advantages of high sensitivity and rapid action.

[0015] In one embodiment of the present invention, the power distribution unit includes an intelligent switch device, a reactive power compensation device and a distributed power supply access interface.

[0016] The intelligent switch equipment includes intelligent circuit breakers and contactors. These switch equipment can receive control instructions from the central control unit to achieve remote operation and automatic control. For example, the intelligent circuit breaker can automatically open and close according to the control strategy, quickly cut off the faulty line when a fault occurs, and switch the line according to the predetermined plan when the power distribution is adjusted. At the same time, the intelligent switch equipment also has a status monitoring function, which can feed back its own opening and closing status, contact wear and other information to the central control unit in real time, which is convenient for operation and maintenance personnel to manage and maintain the equipment.

[0017] The reactive power compensation device includes a capacitor bank, a reactor, and a thyristor switching switch. According to the reactive power compensation control instruction of the central control unit, the capacitor bank is accurately switched in or out through the thyristor switching switch to achieve dynamic compensation of reactive power. The reactor is used to suppress problems such as inrush current and harmonic amplification that may occur when the capacitor is switched in, ensure the stable operation of the reactive power compensation device, improve the power factor of the distribution system, reduce reactive power loss, and improve the quality of power.

[0018] With the widespread application of distributed power sources (such as solar photovoltaic power generation, wind power generation, etc.), this distribution system is equipped with a special distributed power access interface. The interface has functions such as power quality detection, power control, and island protection. For example, when a distributed power source is connected, the quality of its output power is first detected to ensure that it meets the requirements of the distribution system; then, according to the power demand of the distribution system and the power generation capacity of the distributed power source, the output power of the distributed power source is adjusted through the power control module to achieve coordinated operation of the distributed power source and the distribution system; when the main power supply of the distribution system fails and the power is cut off, the island protection function is quickly activated to prevent the distributed power source from independently supplying power to the fault area, thereby ensuring the safety of personnel and equipment.

[0019] In one embodiment of the present invention, the human-computer interaction unit includes a display screen, an operation panel and an alarm device.

[0020] When an abnormal situation occurs in the power distribution system, the alarm device emits an audible and visual alarm signal. The sound and light of the alarm device can be differentiated according to different alarm types. For example, the overcurrent alarm uses a tweeter and a red flashing light, and the leakage alarm uses an intermittent buzzer and a yellow light, so that the operation and maintenance personnel can quickly determine the fault type and location according to the alarm signal and take corresponding treatment measures in time.

[0021] The beneficial effects of the present invention are:

[0022] An intelligent power distribution system of the present invention realizes comprehensive monitoring, intelligent control, efficient protection and flexible power distribution of the power distribution system through the collaborative work between various units, effectively improves the reliability, stability, energy utilization efficiency and intelligence level of the power distribution system, can meet the growing demand and higher quality requirements for power supply in modern society, and has broad application prospects and significant economic benefits.

The smoke sensor can use a photoelectric smoke sensor. Once smoke is detected, it will immediately trigger an alarm to indicate that there may be a fire hazard and ensure the safe operation of the power distribution system.

[0032] The data transmission module transmits the collected power parameters and environmental parameters to the central control unit through a combination of wired (such as Ethernet, RS485, etc.) and wireless (such as Wi-Fi, Bluetooth, 4G / 5G, etc.). For communication between devices with high real-time requirements and short distances, high-speed Ethernet connection is preferred; for some monitoring points that are more dispersed and inconvenient to wire, wireless communication is used to ensure that data can be transmitted stably and quickly, realizing comprehensive monitoring and data sharing of the entire distribution system.

[0033] After the data processing and analysis module receives various data from the intelligent monitoring unit, the module uses advanced algorithms to process and analyze the data. For example, the fast Fourier transform (FFT) algorithm is used to perform spectrum analysis on the collected voltage and current signals to detect whether there is harmonic pollution and calculate the harmonic content.

When environmental parameters are abnormal, corresponding protection measures or alarm mechanisms are activated according to preset rules. For example, when the temperature is too high, the heat dissipation device (such as fan, air conditioner, etc.) is automatically started, and an alarm message is sent to the operation and maintenance personnel.

[0034] The control strategy generation module generates corresponding control strategies based on the results of data processing and analysis. For example, during the peak period of power load, by optimizing the power distribution algorithm, the power supply of important loads is prioritized, and appropriate power restriction or peak-shifting control is performed on non-critical loads. For the case of low power factor, reactive power compensation control instructions are generated to control the reactive power compensation device to put in or remove the capacitor bank to improve the power factor and reduce reactive power loss.

[0035] In addition, the module also has adaptive control capabilities, which can automatically adjust the control strategy according to the operating status of the distribution system and changes in the external environment to ensure that the distribution system is always in the best operating state.

[0036] The intelligent protection unit includes an overcurrent protection module, an overvoltage protection module and a leakage protection module.

[0037] The overcurrent protection module monitors the current in the distribution line in real time, and quickly initiates the protection action when the current exceeds the preset overcurrent protection threshold. By combining fast fuses and intelligent electronic trips, the fast fuses can instantly cut off large current faults and play a role in short-circuit protection; the intelligent electronic trip can achieve overload protection and selective protection according to the current size and duration, avoiding power outages in the entire distribution system due to local faults.

[0038] The overvoltage protection module monitors the voltage value. When the voltage exceeds the set upper limit, the voltage is limited or discharged through devices such as voltage regulators or lightning arresters to protect the power distribution equipment from the impact of excessive voltage. For example, a metal oxide lightning arrester is used, which has good nonlinear volt-ampere characteristics and presents a high resistance state under normal voltage. When the voltage is too high, the resistance decreases rapidly, and the overvoltage energy is introduced into the ground, ensuring the safe and stable operation of the power distribution system.

[0039] The leakage protection module detects the leakage current in the distribution line. Once the leakage current exceeds the safety threshold, the power supply is immediately cut off to prevent electric shock accidents. The residual current operated protector (RCD) is used, which determines whether there is leakage by detecting the vector sum of the live and neutral currents. It has the advantages of high sensitivity and rapid action.

[0040] The power distribution unit includes an intelligent switch device, a reactive power compensation device and a distributed power supply access interface.

[0041] The intelligent switch equipment includes intelligent circuit breakers and contactors. These switch equipment can receive control instructions from the central control unit to achieve remote operation and automatic control. For example, the intelligent circuit breaker can automatically open and close according to the control strategy, quickly cut off the faulty line when a fault occurs, and switch the line according to the predetermined plan when the power distribution is adjusted. At the same time, the intelligent switch equipment also has a status monitoring function, which can feed back its own opening and closing status, contact wear and other information to the central control unit in real time, which is convenient for operation and maintenance personnel to manage and maintain the equipment.

[0042] The reactive power compensation device includes a capacitor bank, a reactor, and a thyristor switching switch. According to the reactive power compensation control instruction of the central control unit, the capacitor bank is accurately switched in or out through the thyristor switching switch to achieve dynamic compensation of reactive power. The reactor is used to suppress problems such as inrush current and harmonic amplification that may occur when the capacitor is switched in, ensure the stable operation of the reactive power compensation device, improve the power factor of the distribution system, reduce reactive power loss, and improve the quality of power.

[0043] With the widespread application of distributed power sources (such as solar photovoltaic power generation, wind power generation, etc.), this distribution system is equipped with a special distributed power access interface. The interface has functions such as power quality detection, power control, and island protection. For example, when a distributed power source is connected, the quality of its output power is first detected to ensure that it meets the requirements of the distribution system; then, according to the power demand of the distribution system and the power generation capacity of the distributed power source, the output power of the distributed power source is adjusted through the power control module to achieve coordinated operation of the distributed power source and the distribution system; when the main power supply of the distribution system fails and the power is cut off, the island protection function is quickly activated to prevent the distributed power source from independently supplying power to the fault area, thereby ensuring the safety of personnel and equipment.

[0044] The human-machine interaction unit comprises a display screen, an operation panel and an alarm device.

[0045] When an abnormal situation occurs in the power distribution system, the alarm device emits an audible and visual alarm signal. The sound and light of the alarm device can be differentiated according to different alarm types. For example, the overcurrent alarm uses a tweeter and a red flashing light, and the leakage alarm uses an intermittent buzzer and a yellow light, so that the operation and maintenance personnel can quickly determine the fault type and location according to the alarm signal and take corresponding treatment measures in time.

[0046] An implementation method of an intelligent power distribution system in this embodiment is as follows:

[0047] According to the design requirements of the power distribution system, the sensors of the intelligent monitoring unit are installed on the corresponding power distribution lines and equipment to ensure that the installation position of the sensors is accurate and firm, and the required power parameters and environmental parameters can be accurately collected. For example, the current sensor should be installed at the incoming line end of the distribution line or on each branch line, and the temperature sensor should be installed at the key heating parts of the distribution equipment (such as transformer windings, near the contacts of the switch cabinet, etc.).

[0048] Install the central control unit, intelligent protection unit, power distribution unit and related equipment of the human-machine interaction unit, and make wiring connections. The wiring should follow the electrical specifications to ensure that the line connection is correct and reliable, and avoid problems such as short circuits and open circuits. After the connection is completed, conduct a comprehensive inspection and debugging of the entire system, including self-testing of hardware equipment, testing of communication lines, initialization of software programs, etc.

[0049] The data collected by the intelligent monitoring unit is calibrated to ensure the accuracy of the data. For example, a standard voltage source and current source are used to calibrate the voltage sensor and the current sensor, and the output signal of the sensor is adjusted to match the actual measured value. At the same time, the sensors of the environmental monitoring module are also calibrated accordingly, such as using a standard humidity generator to calibrate the humidity sensor.

[0050] During the normal operation of the system, the intelligent monitoring unit continuously collects power parameters and environmental parameters, and transmits the data to the central control unit through the data transmission module. The data processing and analysis module of the central control unit processes and analyzes the data in real time, such as calculating the real-time power and power factor of the power system, and monitoring whether the ambient temperature and humidity are within the normal range.

[0051] According to the data analysis results, the control strategy generation module of the central control unit generates corresponding control instructions and sends them to the intelligent switchgear and reactive power compensation device of the power distribution unit. For example, when the power factor is lower than the set value, the reactive power compensation device is controlled to put into the appropriate capacitor bank for reactive power compensation; when a load current is too large and may cause overload, the intelligent switchgear is controlled to limit the power supply of the load or switch to the backup line for power supply.

[0052] The intelligent protection unit monitors the operating status of the power distribution system in real time. Once it detects faults such as overcurrent, overvoltage, and leakage, it immediately starts the protection action, cuts off the faulty line or equipment, and sends a fault signal to the central control unit. After receiving the fault signal, the central control unit records the fault information on the one hand, and sends an alarm message to the operation and maintenance personnel through the display screen and alarm device of the human-machine interaction unit on the other hand, indicating the fault type, location, and occurrence time, etc.

[0053] The operation and maintenance personnel can check the operating parameters, equipment status and alarm information of the power distribution system at any time through the display screen and operation panel of the human-machine interaction unit. When manual intervention is required, such as manual opening and closing of the switch and adjustment of control parameters in an emergency, the corresponding operations can be performed through the operation panel. At the same time, the operation and maintenance personnel can also perform regular maintenance and inspection of the power distribution system based on the historical data and alarm records of the system operation, such as replacing aging equipment and cleaning dust on the surface of sensors, to ensure the long-term stable operation of the power distribution system.

[0054] Some steps in the embodiments of the present invention may be implemented using software, and the corresponding software program may be stored in a readable storage medium, such as a CD or a hard disk.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
