Description

Technical Field

[0001] The present application relates to the field of classified technology for the construction of smart hydropower plants, and in particular to a method and device for intelligently controlling the power consumption rate of a large hydropower plant. Background Art

[0002] The power consumption rate is the ratio of power consumption of equipment and facilities to power generation in the same period of power generation, and is one of the important production indicators to measure the economic benefits of power plants. At present, the power consumption rate of hydropower plants in my country is generally between 0.1% and 2%. When large hydropower stations are in operation, the power consumption rate of hydropower plants generally accounts for about 2% to 5% of the total power generation.

[0003] With the growth of energy demand and price fluctuations, the control of power consumption rate of hydropower plants has become an important part of power plant management and an important energy-saving direction, which is directly related to the economic benefits of power generation enterprises and the effectiveness of energy conservation and consumption reduction. The main factors affecting the power consumption rate of hydropower plants are: (1) Auxiliary equipment power consumption: Various auxiliary equipment in hydropower plants, such as oil pumps, drainage pumps, ventilation and cooling systems, are the main consumers of power consumption. The operating efficiency and status of these equipment directly affect the power consumption rate; (2) Building scale and lighting: Hydropower plants have large buildings, widely distributed sites, and many lighting equipment. Lighting power consumption is also an important part of power consumption; (3) Ambient temperature and ventilation: In order to maintain the ambient temperature and ensure the safe operation of equipment, hydropower plants need to operate a large number of ventilation and cooling equipment such as air conditioners and fans. The power consumption of these equipment varies with the changes in ambient temperature.

[0004] Controlling the power consumption rate of a hydropower plant is a complex and important task that requires comprehensive measures from multiple aspects. Because the actual power generation of a hydropower plant deviates greatly from the annual planned power generation, in order to ensure that the power consumption rate reaches the control target, it is necessary to accurately control the power consumption of the plant based on the actual power generation.

[0005] The current factory power control methods are mostly based on static planning, which lack flexibility and are difficult to adapt to the needs of fluctuating power generation. Summary of the invention

[0067] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0068] In order to realize the refined intelligent control of the power consumption of hydropower plants, save electricity while ensuring normal load power supply, and reduce the workload of manual control, so as to achieve the purpose of reducing costs and increasing efficiency, the embodiment of the present application proposes a method for intelligent control of the power consumption rate of large hydropower plants. Figure 1 This is a flow chart of a method for intelligently controlling the power consumption rate of a large hydropower plant provided in an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0069] Step S1, using a plant power load classification method to divide the plant power load into fixed load and adjustable load.

[0070] In the embodiment of the present application, the plant power load classification method is used to divide the plant power load into fixed load and adjustable load. The purpose of this classification is to clarify the characteristics of each part of the plant power load so as to take targeted optimization measures for different types of loads in subsequent regulation.

[0071] Specifically, fixed loads are the electricity required for the normal operation of the plant, including lighting power required for basic plant work, power required for maintenance equipment operation, power required to maintain basic operation of the ventilation system, and power required by the unit itself. These loads have rigid demands. Regardless of changes in production load, this part of the electricity consumption needs to remain relatively stable during operation, making it difficult to adjust and optimize.

[0072] The adjustable load is more flexible than the fixed load, and mainly includes ventilation and lighting electricity that exceeds the basic demand. This part of electricity consumption is greatly affected by external environmental conditions, production tasks and personnel activities. For example, when the ambient temperature of the factory is high or the production tasks are busy, the electricity demand of the ventilation system and lighting system may increase, while when the ambient temperature is suitable or during non-working hours, this part of electricity consumption has a large room for optimization.

[0073] In the embodiments of the present application, by reasonably classifying the plant power load, the foundation can be laid for the subsequent load optimization control. In particular, for the adjustable load part, it can be dynamically adjusted according to the power generation plan and actual operation through intelligent means. For example, under the premise of ensuring the operation of equipment and the safety of personnel, unnecessary ventilation power consumption can be reduced by optimizing the operation mode of the ventilation system, or the lighting power consumption in non-essential areas can be reduced through the intelligent lighting control system, thereby effectively reducing the overall plant power consumption rate. This classification method not only improves the pertinence of load control, but also provides basic data support and logical framework for achieving the energy-saving and consumption-reduction goals of hydropower plants.

[0074] Step S2, according to the annual, monthly and daily planned power generation, the annual, monthly and daily adjustable plant power loads are calculated respectively, and the adjustable load control power for the next day is determined by a step-by-step association method.

[0075] Specifically, step S2 includes the following steps:

[0076] S21, calculates the remaining monthly adjustable load based on the annual planned power generation, the annual actual power generation, the annual actual power consumption and the planned power consumption rate, providing basic data for monthly regulation.

[0077] In the embodiment of the present application, the annual available plant power load and balance are calculated by annual planned power generation, actual power generation and plant power rate, and further decomposed into monthly and daily loads. The calculation of annual load provides the overall framework of the entire control strategy to ensure the controllability of the annual plant power rate target.

[0078] Specifically, the following parameters are calculated in turn:

[0079] (1) Calculate the annual planned power consumption of the plant. The annual planned power consumption of the plant reflects the power demand of the plant corresponding to the annual planned power generation. The calculation formula is: annual planned power consumption of the plant = annual planned power generation × planned power consumption rate of the plant.

[0080] (2) Calculate the monthly planned power consumption. The annual planned power consumption is evenly divided into each month to obtain the monthly planned power consumption. The calculation formula is: annual planned power consumption / 12.

[0081] (3) Calculate the monthly planned adjustable power load. The monthly planned adjustable power load is the result of subtracting the monthly fixed power load from the monthly planned power consumption. The calculation formula is: monthly planned adjustable power load = monthly planned power consumption - monthly fixed power load.

[0082] It should be noted that the monthly fixed plant power load needs to be determined based on the actual situation of each hydropower plant, and this application does not make any specific restrictions on this.

[0083] (4) Calculate the planned power consumption of the factory as of the end of this year. The planned power consumption of the factory as of the end of this year is the power demand of the factory calculated based on the actual power generation in the year. The calculation formula is: planned power consumption of the factory as of the end of this year = annual power generation × planned power consumption rate.

[0084] (5) Calculate the annual surplus adjustable power load. The annual surplus adjustable power load is the difference between the power consumption up to the current time and the actual power consumption. The calculation formula is: annual surplus adjustable power load = planned power consumption up to the current time this year - power consumption used this year.

[0085] (6) Calculate the annual remaining available power load. The annual remaining available power load comprehensively considers the annual planned power consumption, the used power consumption and the annual surplus load. The calculation formula is: Annual remaining available power load = annual planned power consumption - the used power consumption this year + the annual surplus adjustable power load.

[0086] It should be noted that when the annual surplus adjustable factory electricity load is a negative value, it means that the factory electricity consumption used this year exceeds the planned factory electricity consumption as of the current date of this year.

[0087] (7) Calculate the remaining average monthly available plant power load. The remaining average monthly available plant power load reflects the average distribution of the annual remaining load in the remaining months. The calculation formula is: annual remaining available plant power load / remaining months.

[0088] (8) Calculate the remaining average monthly adjustable power load. The remaining average monthly adjustable power load is the average adjustable load after deducting the fixed load. The calculation formula is: remaining average monthly adjustable power load = remaining average monthly available power load - monthly fixed power load.

[0089] Through the above steps, the remaining monthly adjustable plant power load is gradually calculated and obtained, which provides key basic data for subsequent monthly and daily regulation and control, ensuring the rationality and scientificity of load regulation.

[0090] S22, calculates the remaining daily average adjustable load based on the monthly planned power generation, the monthly actual power generation, the monthly actual power consumption and the planned power consumption rate, providing basic data for daily control.

[0091] The embodiment of the present application calculates the monthly remaining adjustable load at the monthly level based on the monthly planned power generation, the monthly actual power generation and the plant power consumption data. The monthly calculation process associates the annual data so that the monthly load regulation meets the monthly load distribution requirements and is consistent with the annual target. This step-by-step association method ensures the coherence of the regulation logic and the hierarchical realization of the goals.

[0092] Specifically, the following parameters are calculated in turn:

[0093] (1) Calculate the monthly planned power consumption. The monthly planned power consumption is calculated based on the monthly planned power generation and the planned power consumption rate. It is used to measure the overall demand for monthly power consumption. The calculation formula is: monthly planned power consumption = monthly planned power generation × planned power consumption rate.

[0094] (2) Calculate the daily planned power consumption. The daily planned power consumption is obtained by evenly distributing the monthly planned power consumption to each day. It is used to measure the daily power demand of the factory. The calculation formula is: daily planned power consumption = monthly planned power consumption / 30.

[0095] (3) Calculate the daily planned adjustable power load. The daily planned adjustable power load is the adjustable part after deducting the daily fixed power load. The calculation formula is: daily planned adjustable power load = daily planned power consumption - daily fixed power load.

[0096] (4) Calculate the planned power consumption of the factory as of this month. The planned power consumption of the factory as of this month is calculated based on the current power generation and the planned power consumption rate. The calculation formula is: planned power consumption of the factory as of this month = monthly power generation × planned power consumption rate.

[0097] (5) Calculate the current month's balance of adjustable power load. The current month's balance of adjustable power load is calculated by comparing the current planned power consumption and the used power consumption of the current month. The calculation formula is: current month's balance of adjustable power load = current month's plan power consumption - used power consumption of the current month.

[0098] (6) Calculate the remaining available power load for the month. The remaining available power load for the month comprehensively considers the planned power consumption for the month, the actual power consumption and the remaining load for the month, and reflects the remaining available load within the month. The calculation formula is: The remaining available power load for the month = the planned power consumption for the month - the power consumption for the month already used + the remaining adjustable power load for the month.

[0099] It should be noted that when the monthly balance adjustable factory power load is a negative value, it means that the factory power consumption used this month exceeds the current planned factory power consumption as of the end of this month.

[0100] (7) Calculate the remaining daily average available plant power load. The remaining daily average available plant power load is the result of allocating the monthly remaining available plant power load to the remaining days in the month. The calculation formula is: remaining daily average available plant power load = monthly remaining available plant power load / remaining days in the month.

[0101] (8) Calculate the remaining daily average adjustable power load. The remaining daily average adjustable power load is obtained by deducting the daily fixed power load from the remaining daily average available power load. The calculation formula is: remaining daily average adjustable power load = remaining daily average available power load - daily fixed power load.

[0102] Through the above calculation steps, the remaining daily average adjustable plant power load is gradually obtained, providing basic data for daily load control. This process ensures the dynamic connection between the monthly control target and the daily control target, making daily load control more accurate and efficient.

[0103] S23, calculates the daily available adjustable load based on the daily planned power generation and the planned plant power consumption rate, providing basic data for daily regulation.

[0104] The embodiment of the present application calculates the daily available adjustable load at the daily level by combining the daily planned power generation and the plant power consumption rate, while considering the impact of the monthly surplus load on the daily load distribution. Through this process, the daily plant power load distribution is dynamically adjusted to meet the production and equipment operation needs and to have a reasonable proportion in the overall load. The correlation between monthly and daily loads ensures that daily regulation can respond to upper-level goals and provide guidance for real-time optimization.

[0105] Specifically, it is first necessary to calculate the daily factory electricity demand based on the daily planned power generation and the planned factory electricity consumption rate to measure the total factory electricity demand on the day. The calculation formula is: daily planned factory electricity consumption = daily planned power generation × planned factory electricity consumption rate.

[0106] Then calculate the daily available regulating load. The daily available regulating load is the dynamically adjustable load obtained by deducting the fixed power load from the daily planned power consumption. The calculation formula is: daily available regulating load = daily planned power consumption - daily fixed power load.

[0107] Through the above steps, the calculated daily available adjustable load provides accurate basic data for daily load regulation, and can also provide flexibility for daily load adjustment and optimization distribution in combination with the actual dynamic power consumption situation. This ensures that the basic needs of production and operation are met, and energy-saving optimization goals can be achieved through intelligent control methods.

[0108] S24, associating the annual, monthly and daily electricity consumption plans, obtaining the daily balance taking into account the monthly balance, and further calculating the adjustable load power for the next day.

[0109] In the embodiment of the present application, the adjustable load power for the next day is calculated by comprehensively considering factors such as the daily available adjustable load and the power balance.

[0110] Specifically, the following parameters are calculated in turn:

[0111] (1) Calculate the monthly balance considering the annual balance. The monthly balance of the annual balance is calculated based on the combination of the annual surplus load and the monthly surplus load, and is used to measure the load adjustment space of the current month in the annual plan. The calculation formula is: The calculation formula of the monthly balance of the annual balance is: Monthly balance of the annual balance = Annual surplus adjustable load / Number of remaining months in this year + Monthly surplus load.

[0112] (2) Calculate the adjustable load for this month. The adjustable load for this month is obtained by comparing the monthly balance of the annual balance with the preset threshold, and is used to clarify the actual available adjustment range within the month. The calculation formula is: when the monthly balance considering the annual balance is less than the preset threshold, the adjustable load for this month = the monthly balance considering the annual balance - the preset threshold; when the monthly balance considering the annual balance is greater than or equal to the preset threshold, the adjustable load for this month = 0.

[0113] It should be noted that the threshold can be flexibly adjusted and set according to the specific scenario. The initial plan is to set it to 10kWh.

[0114] (3) Calculate the daily balance of the monthly balance. The daily balance of the monthly balance is calculated based on the adjustable load of the current month and the daily available adjustable load. It is used to measure the actual daily load adjustment space. The calculation formula is:

[0115] When the adjustable load of this month = 0, the daily balance of the monthly balance = 0; when the adjustable load of this month ≠ 0, the daily balance of the monthly balance = daily available adjustable load + adjustable load of this month / remaining days.

[0116] (4) Calculate the next day's adjustable load power. The next day's adjustable load power comprehensively considers the daily available adjustable load and the daily balance of the monthly balance to obtain the actual load adjustment capacity of the next day. The calculation formula is: the next day's adjustable load power = daily available adjustable load + daily balance of the monthly balance.

[0117] Through the above steps, the annual, monthly and daily power consumption plans are effectively linked, and the load distribution is refined and adjusted step by step. The final adjustable load power for the next day provides an accurate data basis for daily control, ensuring that load control can be flexibly adjusted under the annual target and monthly constraints.

[0118] S25, dividing the available plant power load for the next day by 24 hours to obtain the adjustable load control power for the next day.

[0119] Finally, the next day's adjustable load control power is obtained based on the calculated next day's available plant power load by evenly distributing it over the 24 hours of the day, and is used to guide the next day's dynamic load regulation.

[0120] The calculated adjustable load control power for the next day is used as the core parameter for dynamic load regulation to ensure the real-time and flexibility of load regulation. Based on this power value, the precise distribution of factory power load in different time periods can be achieved while ensuring the safety of equipment operation and production needs.

[0121] The embodiment of the present application adopts a step-by-step association method to decompose the annual target step by step into monthly and daily levels, and combines real-time power generation, power consumption and other data to ensure the linkage matching of load regulation and actual operating conditions. This logic ensures that under the constraint of the annual total goal, the load distribution of each time scale is optimized step by step, so that the regulation process is consistent with long-term planning and can quickly respond to short-term fluctuations. In addition, the calculation of the adjustable load control power of the next day provides accurate reference data for the subsequent dynamic adjustment of plant power consumption, supports flexible switching of modes during the operation of adjustable loads such as ventilation and lighting, and achieves energy-saving optimization goals to the greatest extent, while improving the economy and efficiency of hydropower plant operation.

[0122] Step S3, dynamically adjusting the operation mode of the adjustable load for the factory power supply according to the calculated adjustable load control power for the next day.

[0123] In the embodiment of the present application, the ventilation system and lighting system in the factory power supply are divided into multiple operation modes according to different operation requirements and energy-saving targets, and the operation parameters of the equipment in each mode are dynamically adjusted according to the adjustable load control power of the next day. The control logic is as follows: Figure 2 As shown, the details are as follows:

[0124] (1) The ventilation system is divided into energy-saving mode, maintenance mode and normal mode according to the operation requirements. The operating status of the equipment in different modes is as follows:

[0125] Energy-saving mode: The ventilation required by important equipment in the whole plant is maintained at the minimum operating mode to ensure basic ventilation needs. Except for the necessary ventilation required by the equipment or factory environment, other fans or air conditioners are stopped to minimize energy consumption.

[0126] Maintenance mode: When a power plant is carrying out maintenance on a unit or an area needs emergency treatment, the fans or air conditioners of the corresponding units or area sections are all started at the maximum operating mode to ensure the smooth progress of maintenance and emergency treatment.

[0127] Normal mode: The ventilation required for important equipment in the entire plant is maintained in the optimal operating mode. At the same time, the factory environment maintains the comfortable air volume required for the staff to work, meeting normal production and operation needs.

[0128] (2) The lighting system is divided into energy-saving mode, maintenance mode, normal mode and visit mode according to operating requirements. The operating status of each mode is as follows:

[0129] Energy-saving mode: The lighting system of the entire plant only ensures basic lighting for the staff's work. Except for the lighting in important areas which remains in the minimum operating mode, all other lighting is stopped to reduce energy consumption.

[0130] Maintenance mode: When a power plant is carrying out maintenance work on a unit or an area, the lighting in the corresponding area will be fully operated at the maximum operating mode to provide sufficient lighting conditions for the maintenance and inspection.

[0131] Normal mode: The lighting system of the entire plant ensures the work of the staff, and the lighting in important areas maintains the optimal operation mode to meet the lighting needs of normal production activities.

[0132] Visiting mode: The lighting of the entire factory is operated at the maximum operating mode, especially the lighting of display areas such as the cultural corridor and cultural exhibition hall is kept in operation around the clock, which is suitable for visiting and publicity activities.

[0133] When applied in actual scenarios, the above-mentioned operation modes can be embedded and written into the control system programs of the ventilation system and the lighting system, and the operation modes of the ventilation and lighting systems can be dynamically switched according to the calculated adjustable load control power of the next day. Therefore, under the principle of energy saving and consumption reduction, the operators of the hydropower plant can choose different control strategies according to various factors such as operation mode, living electricity, environmental control and on-site operation requirements, so as to achieve one-key control, thereby achieving the purpose of flexible and precise control of plant electricity consumption, effectively reducing the plant electricity consumption rate, improving the economic benefits of power generation enterprises and the effectiveness of energy saving and consumption reduction work, and having significant economic benefits and promotion value. In addition, through the reasonable allocation of each mode, it not only ensures the safety of production operation and equipment, but also realizes the flexible adjustment of plant power load and efficient use of energy. This dynamic control method based on mode switching helps to significantly reduce the plant power consumption rate and improve the economic benefits and energy saving effect of hydropower plants.
