[0074] Reference Figure 3 As shown, the programming operation module specifically includes:

[0075] Logical judgment unit: According to preset rules and algorithms, it analyzes and judges the collected data in real time and issues corresponding control instructions in a timely manner;

[0076] Electricity calculation unit: accurately calculates the electricity consumption of the power distribution system and provides accurate data support for electricity bill settlement and energy-saving analysis;

[0077] Power quality management unit: Active filtering device is used to suppress harmonic current, and reactive power compensation device is used to increase power factor and improve power quality.

[0078] Algorithm optimization unit: Using advanced dynamic algorithms, it continuously optimizes control strategies based on real-time data and the operating status of the distribution system to improve the intelligence level and operating efficiency of the distribution system.

[0079] The power quality management unit specifically includes:

[0080] Harmonic current is an important indicator of power quality issues. It is used to measure the degree of current distortion in the distribution system. The harmonic current calculation formula is:

[0081]

[0082] In the formula, I THD is the total harmonic distortion rate, which indicates the proportion of harmonic current to total current; I m is the effective value of the mth harmonic current; I 1 is the effective value of the fundamental current.

[0083] It should be noted that active filtering devices: In modern power distribution systems, the use of a large number of nonlinear loads will generate harmonic currents, which will cause equipment heating, increased losses, inaccurate measurement, etc. Active filtering devices monitor harmonic currents in real time and generate compensation currents that are equal in magnitude and opposite in direction to the harmonic currents, thereby effectively suppressing harmonic currents and improving power quality.

[0084] Reactive power compensation device: Reactive power will increase the current in the power grid, increase line loss and transformer loss. Reactive power compensation devices provide or absorb reactive power to the distribution system by inserting or removing capacitors, etc., to improve the power factor, reduce the transmission of reactive power, reduce losses, and improve the operating efficiency of the power grid.

[0085] The logic judgment unit specifically includes:

[0086] In a complex power distribution system, multiple parameters need to be combined for judgment, and the weighted logic judgment formula is:

[0087] S=w1 p 1 +w 2 p 2 +w 3 p 3 +…+w n p n

[0088] If S>S threshould , a control command is issued

[0089] In the formula, S is the comprehensive score and status value, w 1 ,w 2 ,w 3 ,...,w n is the weight coefficient of each parameter, which is set according to the importance of the parameter, p 1 ,p 2 ,p 3 ,...,p n For different parameter values, such as current, voltage, temperature, S threshould is the threshold of the comprehensive score.

[0090] The algorithm optimization unit specifically includes:

[0091] Calculation formula:

[0092]

[0093] Where V(t,x) is the optimal value function of state x at time t; u is the control variable, such as reactive compensation and active filtering; C(t,x,u) is the cost function of the current stage, such as energy consumption and deviation degree; x' is the state of the next stage.

[0094] The specific functions of the logic judgment unit are:

[0095] 1. Fault diagnosis:

[0096] Overcurrent judgment: By real-time monitoring of the current value in the power distribution system, it is compared with the pre-set overcurrent threshold. If the current value exceeds the threshold and lasts for a certain period of time, the logic judgment unit determines it as an overcurrent fault; for example, when the normal operating current of the line is 100A, the overcurrent threshold is set to 120A, and when the monitored current reaches 130A and lasts for 3 seconds, the power distribution system determines it as an overcurrent fault.

[0097] Overvoltage and undervoltage judgment: The voltage data of the distribution system is collected in real time and compared with the set overvoltage and undervoltage thresholds. When the voltage is higher than the overvoltage threshold or lower than the undervoltage threshold, the corresponding fault is determined. For example, the normal voltage range is set to 360V-400V, the overvoltage threshold is 410V, and the undervoltage threshold is 350V. When the voltage reaches 420V or 340V, the distribution system makes a judgment.

[0098] Ground fault judgment: Use zero-sequence current transformer and other equipment to monitor zero-sequence current. When the zero-sequence current exceeds the set ground fault threshold, it is determined that there is a ground fault; because in normal operation, the three-phase current is balanced and the zero-sequence current is very small; when a ground fault occurs, a larger zero-sequence current will be generated.

[0099] 2. Operation status judgment

[0100] Equipment switching status judgment: By monitoring the auxiliary contact signal of the switch device, it is judged whether the switch is in the closed or open state. For example, when the auxiliary contact closing signal is fed back to the logic judgment unit, it is judged that the switch is in the closed state and the equipment is put into operation; otherwise, it is in the open state and the equipment is out of operation.

[0101] Load status judgment: Based on the collected current, power and other data, judge whether the load of the distribution system is in a light load, full load or overload state. For example, when the load power is less than 30% of the rated power, it is judged as light load; between 80%-100% is full load; and more than 100% is overload.

[0102] 3. Protection action logic judgment

[0103] Selective protection judgment: When a fault occurs in the power distribution system, the logic judgment unit needs to determine which protection device should be activated based on the location of the fault and the action time limit of the protection device to achieve selective protection. For example, in a multi-level power distribution system, when a fault occurs in the lower-level line, the lower-level protection device should be activated and tripped first, while the upper-level protection device should not be activated to reduce the scope of power outage.

[0104] Reclosing logic judgment: For some instantaneous faults, after the protection device trips, the logic judgment unit will determine whether to perform the reclosing operation based on the preset reclosing logic. If it is determined that the fault has been eliminated, a reclosing command will be issued; if the fault still exists, reclosing is prohibited.

[0105] Reference Figure 4 As shown, the control module specifically includes:

[0106] CPU unit: As the core processor of the control module, it has high-speed computing capability and powerful data processing capability, and can process various control instructions and data in real time;

[0109] Power supply unit: provides stable power supply to the control module to ensure the reliable operation of the power distribution system.

[0110] like Figure 7 The reactive power compensation filter principle diagram is shown in the figure. The current flowing through the load and i L The current flowing from the grid i S ; According to the detected current, calculate the current command that needs to be compensated; According to the output of the command current operation circuit, generate a control signal to control the compensation current generating circuit; According to the control signal, generate the compensation current i C , to offset the reactive power and harmonics generated by the load; drive the compensation current generating circuit so that it can generate the required compensation current.

[0111] In this way, the reactive power compensation filter can effectively reduce the reactive power and harmonics in the power grid, improve the utilization efficiency of electric energy, reduce power grid losses and protect the distribution system.

[0122] y=f ML (X)

[0123] Where y is the optimization suggestion, such as energy-saving strategy and maintenance plan; X is the input data, such as distribution system operation data and user demand; f ML It is a machine learning model, including neural network and support vector machine.

[0124] The specific functions of the parameter visualization unit are:

[0125] The display touch panel not only has operation functions but also can display the opening and closing status of each switch, current, voltage, closing time, accumulated power consumption and other real-time information required by users.

[0126] Chart display: For data with trend changes, such as the operating speed of the distribution system and resource utilization, a line chart can be used to display the changing trend over time; for the proportion of each part, such as the resource allocation ratio of different business functions, a pie chart can be used to present it more clearly.

[0127] Dashboard: Suitable for displaying key performance indicators (KPIs), such as the health status of the power distribution system, task completion progress, etc., allowing users to quickly understand the overall operating status of the power distribution system in an intuitive way.

[0128] Table: When detailed parameter data needs to be displayed, such as specific configuration parameter values, various technical indicators of the power distribution system, etc., the table can clearly present each data, making it convenient for users to view and compare.

[0129] Data update: To ensure that users obtain the latest information, the parameter visualization unit needs to update data in real time or regularly. For data with high real-time requirements, such as the real-time flow of the power distribution system and the current operating status, real-time updates are adopted; for data that changes relatively slowly, such as the basic configuration information of the power distribution system, regular updates can be set.

[0130] The specific functions of the operation control unit are:

[0131] Parameter adjustment: Users can modify the parameters of the power distribution system directly on the display touch panel, such as adjusting the operating frequency of the power distribution system, changing the working mode of the power distribution system, etc. The power distribution system will check the legality of the parameters entered by the user to ensure that the parameters are within a reasonable range;

[0132] Task operation: supports users to control tasks in the power distribution system, such as starting, pausing, stopping tasks, and adjusting task priorities. Through simple operation buttons, users can easily manage the task flow of the power distribution system;

[0133] Equipment control: If the power distribution system involves hardware equipment, the operation control unit can remotely control the hardware equipment wirelessly, such as turning the equipment on or off, adjusting the volume and brightness of the equipment, etc.

[0134] Operation interface layout: The layout of operation buttons and controls should conform to the user's operating habits, and commonly used operations should be placed in a prominent position to avoid user confusion during operation;

[0135] Feedback mechanism: After the user performs an operation, the power distribution system should give timely feedback to inform the user whether the operation is successful. Feedback can be provided by popping up a prompt box, changing the button color, etc.
