Description

Technical Field

[0001] The present invention relates to the technical field of power stabilization, and in particular to a power stabilization analysis system and method based on dual-mode communication. Background Art

[0002] In the modern industrial production process, power supply is an important basis for maintaining the normal operation of the factory. However, with the continuous expansion and complexity of production scale, the demand for power in the factory gradually increases, especially during peak power consumption or when production tasks are more concentrated, the power demand of the factory may exceed its set power limit. In this case, if there is no effective power management strategy, it may cause the power system to overload, which in turn causes power instability and may even cause power outages, seriously affecting the production efficiency and safety of the factory.

[0003] In the existing technology, a maximum power limit is usually set for the factory to ensure that the factory does not exceed the carrying capacity of the power system during the production process. Once the total power consumption of the factory exceeds the set power limit, it is necessary to cut off the power of some equipment to avoid exceeding the maximum power limit. However, this strategy has great limitations. First, a simple power outage may have a great impact on production, especially for some continuous production equipment. Sudden power outages may cause production stagnation, leading to greater economic losses. Secondly, during the deployment process, it is impossible to effectively distinguish the importance and priority of equipment, which may cause some key equipment to stop operating while non-key equipment continues to operate, further reducing production efficiency.

[0004] This method aims to propose a reasonable control of the power equipment in the factory area to avoid the power demand of the factory area exceeding the power limit and ensure the power stability of the factory area. Summary of the invention

[0081] Data calculation module: based on known data, calculates excess power, spare power, total power consumption of each numbered electrical equipment, and quantity ratio;

[0082] Data comparison module: compares the available power with the excess power;

[0083] Numbering module: number the electrical equipment in the factory according to the production sequence;

[0084] Dual-mode communication module: obtains the power consumption information of each power-consuming equipment in the factory area collected by each power stabilization module;

[0085] Start-stop control module: controls the electrical equipment to work normally and stop working intermittently.

[0086] The present invention has the following beneficial effects:

[0087] 1. By setting power limits for the factory, the power consumption can be controlled in advance during the production process of the factory to ensure that the power consumption of the factory does not exceed the safe range, prevent the risk of overload of power equipment due to overload, and thus avoid grid failure or power outage accidents.

[0088] 2. When the production demand of the factory exceeds the power limit, the power allocation strategy is implemented to ensure a balance between production demand and power supply by dynamically adjusting the start and stop of equipment. This strategy can ensure that the production process of the factory will not be completely interrupted due to insufficient power, while avoiding the problem of power overload caused by the simultaneous operation of all equipment. The application of the allocation strategy ensures the continuity of factory production and reduces the economic losses caused by shutdowns.

[0089] 3. Numbering the electrical equipment in the factory according to the production sequence can clearly identify the type and quantity of electrical equipment involved in each production link. This systematic numbering method enables priority selection of equipment with less impact on the production process for start-up and shutdown adjustments during power allocation, thereby minimizing interference with core production links and improving the efficiency of power allocation.

[0090] 4. Obtaining the number of electrical equipment with the same number and selecting the steps to allocate equipment based on the number can ensure that the system gives priority to allocating equipment that has less impact on the production process, thereby ensuring the continuous operation of core equipment. This allocation method not only improves the rational utilization of resources, but also avoids production stagnation or unnecessary energy consumption caused by arbitrary selection of allocation equipment.

[0091] 5. By setting the unit production time, the system can ensure that decimal-numbered electrical equipment works intermittently in different time periods, thereby saving electricity without completely stagnating production; such a flexible adjustment strategy allows the system to maintain stable production while providing spare power for production needs.

[0092] 6. The system gradually compares the spare power and the excess power to reasonably determine the number of deployed equipment that needs to stop working, thereby avoiding over-deployment. This method can prevent the unnecessary shutdown of too many equipment and ensure the maximization of production efficiency. In addition, the gradual deployment strategy can also help the system find the optimal solution, which not only ensures stable power supply, but also does not affect production efficiency, and can minimize interference with production plans.

[0097] Obtain the required power consumption of the plant area, which is recorded as the total power consumption of the plant area;

[0098] When the production demand of the plant exceeds the power limit, the plant will be marked as an over-limit plant, and a power allocation strategy will be implemented for the over-limit plant to stabilize the power required for production in the plant. The production demand may be that the plant needs to temporarily add a new power-consuming equipment, and the addition of this power-consuming equipment increases the total power consumption of the plant, that is, the production demand increases. The power stability means that the total power consumption of the plant is less than the power limit of the plant. When the production demand of the plant exceeds the power limit, the power allocation strategy is implemented to ensure a balance between production demand and power supply by dynamically adjusting the start and stop of equipment. This strategy can ensure that the production process of the plant will not be completely interrupted due to insufficient power, and at the same time avoid the problem of power overload caused by the simultaneous operation of all equipment.
