Description

Technical Field

[0002] A power distribution cabinet is a complete set of devices in a power system used to centrally install switching equipment, measuring instruments, protective electrical appliances, auxiliary equipment, and other components to realize the reception, distribution, control, protection, and monitoring of electrical energy. Power distribution cabinets are often installed in high-temperature, high-humidity, or dusty environments, and their environmental adaptability directly affects operational safety and lifespan. With the increasing growth of power loads and the increasing complexity of power consumption environments, higher requirements are placed on the environmental adaptability of power distribution cabinets. Ensuring the long-term stable operation of power distribution cabinets in complex and changing environments is a key task in power system design and operation and maintenance.

[0003] However, existing power distribution cabinets have significant shortcomings in environmental adaptability. On the one hand, when constructing environmental decision-making mechanisms, existing power distribution cabinets only consider the internal environmental conditions, neglecting the external environmental conditions. They have not established a collaborative decision-making mechanism based on internal needs and external constraints, which easily leads to the introduction of new problems from outside the cabinet after solving old problems inside. On the other hand, existing power distribution cabinets lack the ability to learn and optimize autonomously in terms of environmental self-adaptation. Their environmental adaptation strategies rely on fixed manual settings, while power distribution cabinets cannot dynamically evolve in complex environments, such as equipment aging. Therefore, the original environmental adaptation strategies set by the power distribution cabinets are difficult to maintain accuracy and effectiveness in the long term. Summary of the Invention

[0025] Furthermore, the environmental state recognition model in S2 is specifically as follows: Using cabinet interior environmental data vectors To determine the conditions, a state mapping function for the cabinet is established. Cabinet internal state mapping function Specifically: ; in, , , , , These represent the mapping functions based on the preset cabinet state in the i-th cycle. The corresponding five environmental state modes, This indicates an abnormal humidity level. Indicates an abnormal temperature condition. Indicates the internal pollution status. This indicates the critical state of condensation. Indicates a normal environmental state; This indicates the temperature threshold range inside the cabinet. This indicates the threshold concentration of particulate matter inside the cabinet. This indicates that the cabinet is in a critical state of condensation during the i-th collection cycle. This indicates that there is no risk of condensation inside the cabinet during the i-th collection cycle; Vector the environmental data inside the cabinet Input cabinet internal state mapping function The judgment condition set for the i-th period is obtained. , condition set This includes at least one environmental state mode. Apart from the normal environmental state, these environmental state modes are independent of each other and can coexist simultaneously. For example, before a summer thunderstorm, high humidity, high temperature, and condensation critical conditions may occur simultaneously. (40%, 70%) (15℃, 35℃) for , obtain , , , The mapping yields the set of judgment conditions as follows: .

[0026] Furthermore, the environmental decision rules in S3 use external environmental data as constraints, specifically as follows: External environmental data vector Establish constraint mapping functions. constraint mapping function Specifically: ; in, , These represent the mapping functions for the i-th period based on preset constraints. The corresponding two types of constraints, This indicates that ventilation is permitted. This indicates that ventilation is prohibited. Indicates the humidity threshold range outside the cabinet.

Vector data of the external environment of the cabinet Input constraint mapping function The external constraints of the cabinet in the i-th period are obtained. External constraints of the cabinet for and One of them, for example, before summer thunderstorms, is known (30%, 80%) (10℃, 40℃). , obtain , , The determination is that ventilation is not allowed, meaning the external constraints of the cabinet are... Or, during a sandstorm, to obtain , , The determination is that ventilation is not allowed, meaning the external constraints of the cabinet are... .

[0027] Furthermore, environmental decision-making rules further include: Set up environmental adjustment action set Environmental adjustment action set It includes at least energy-saving standby mode, exhaust operation, cooling operation, heating operation, and internal circulation filtration operation; Establish environmental decision-making rules ,in, Let represent the set of judgment conditions for the i-th period.

[0028] For example, as shown in Table 1, set the environmental decision rules:

[0029] By employing a dual-layer decision-making rule system that considers both the internal environmental state mode and external constraints, the system can intelligently select between exhaust ventilation and internal closed-loop regulation based on the external environment. This avoids secondary pollution caused by blind ventilation in harsh weather conditions such as rain, snow, and sandstorms, which is common in traditional power distribution cabinets. Simultaneously, an energy-saving standby mode is set up under normal environmental conditions to reduce energy consumption, achieving a balance between environmental adaptability and low energy consumption. Through a preset environmental state recognition model and environmental decision-making rules, the power distribution cabinet can adaptively adjust to the environment without requiring manual operation by staff, making it more efficient and intelligent.

[0030] Furthermore, S4 specifically refers to: S41. Evaluate the severity of the environmental state pattern corresponding to each decision action. The severity of the state is determined by the degree of deviation and the risk weight. Calculate the degree of deviation for each environmental state pattern. , This indicates the degree of deviation of environmental state mode j, specifically, when the decision data corresponding to environmental state mode j exceeds the boundary of its decision threshold, the excess amount is divided by the value of the boundary exceeded.

This represents the risk weight of environmental state pattern j; S43. Preset a baseline rate of change for each decision data point. Calculate the rate of change for each decision data point based on the deviation between the current and previous acquisition cycles. Divide the rate of change by the preset baseline rate of change to obtain the rate of occurrence of the environmental state mode. ; S44. Calculate the urgency score for each environmental state mode. ,in The urgency weight indicates the severity of the situation. The urgency weight indicates the rate at which a state occurs; S45. Sort each environmental state mode from highest to lowest according to the urgency score. Sort the decision actions corresponding to the environmental state modes from front to back according to the sorting of the environmental state modes. That is, the higher the urgency of the environmental state mode, the higher the priority of its corresponding decision action, and obtain the optimal decision action set.

[0031] By prioritizing decision-making actions, conflicts can be prevented, and actions with high urgency can be performed first. This ensures that when multiple environmental anomalies occur simultaneously, the power distribution cabinet can prioritize the most urgent protective actions, reducing the risk of equipment damage and safety accidents.

[0032] Furthermore, the decision event includes environmental data, decision actions, and decision results, wherein the decision results include at least the length of time from the start to the end of the decision action, i.e., the execution time; Retrospective analysis includes clustering based on environmental data in decision events and statistically analyzing the decision actions and results of decision events under each environmental state pattern.

[0033] Furthermore, the optimization of the decision threshold is specifically as follows: Decision threshold refers to the state mapping function within the cabinet. Mapping function with constraints The decision thresholds include the humidity threshold range inside the cabinet. Cabinet internal temperature threshold range Particulate matter concentration threshold inside the cabinet External humidity threshold range External temperature threshold range And the threshold of particulate matter concentration outside the cabinet Analyze decision-making events based on the same environmental state pattern: If decision events are frequent and the execution time of decision results is short under the environmental state mode, the decision threshold can be relaxed based on environmental data. If decision events are sparse and execution time is long in the decision results under the environmental state mode, then the decision threshold is tightened based on environmental data.

[0034] Specifically, a certain distribution cabinet has a preset internal temperature threshold range. The temperature range is (15℃, 35℃). A one-month backtracking period is set. After one month, the system performs a backtracking analysis of the historical database and finds 110 decision-making events recorded under high-temperature conditions, with an average execution time of 5 minutes. This determines the temperature threshold range inside the cabinet. Because (15℃, 35℃) is too sensitive, this method automatically adjusts the temperature threshold range. Adjust to (15℃, 36℃).

[0035] By establishing a historical database and setting a backtracking period, and conducting backtracking analysis on the historical database within the backtracking period, adaptive optimization of decision thresholds is achieved. Distribution cabinets in different regions and at different altitudes can automatically optimize and adapt to their environment as operational data accumulates during use, overcoming the shortcomings of traditional distribution cabinets that cannot adapt to dynamic changes such as seasons, regions, and equipment aging due to fixed thresholds.

[0036] Example 2, see Figure 2 An environment-adaptive intelligent monitoring system for power distribution cabinets, used to implement the aforementioned environment-adaptive intelligent monitoring method for power distribution cabinets, includes a data acquisition module, an environmental state identification module, a decision acquisition module, a priority ranking module, a decision execution module, and a backtracking optimization module, wherein... The data acquisition module is used to integrate several environmental acquisition sensors inside the cabinet to collect environmental data during the acquisition period. The environmental data includes environmental data inside the cabinet and environmental data outside the cabinet. The environmental status recognition module is used to match the environmental status recognition model with the external environmental data to obtain the environmental status pattern; The decision acquisition module is used to obtain a set of decision actions by taking the environmental state mode as the judgment condition and the external environmental data as the constraint condition and inputting it into the preset environmental decision rules. The priority sorting module is used to sort the decision actions within the decision action set by priority and obtain the optimal decision action set; The decision execution module is used to execute decision actions based on the optimal set of decision actions and record the decision results; The backtracking optimization module is used to build a historical database, record each decision event, preset the backtracking period, perform backtracking analysis on the historical database according to the backtracking period, and optimize the decision threshold.

[0037] Furthermore, the decision execution module is connected to an exhaust system, a dehumidification system, a refrigeration system, a heating system, and an internal circulation filtration system.
