Description

Technical Field

[0002] Hydropower stations utilize the water cycle to regenerate energy. The power generation process does not consume water resources and emits no pollutants, contributing important value to the construction of the global green energy system. Reasonable power distribution for hydropower station generators can maximize the utilization rate of clean energy, reduce the water abandonment rate, and reduce energy waste. Power distribution in hydropower stations is a core link in balancing energy utilization efficiency and power system security. However, in the actual power distribution scheduling process, the power allocated to hydropower station generators is not fully adapted to themselves. Grid dispatching power generation instructions often only consider grid demand to allocate loads, without considering whether the state of the generators themselves is adapted to the assigned power generation tasks. Some high-efficiency generators are in a low-load operation state for a long time, resulting in the power generation efficiency of the generators deviating from the optimal efficiency area. The existing technology has obvious deficiencies in the current power distribution of hydropower stations. It does not conduct an adaptability analysis of the power allocated to hydropower station generators and the generators, cannot dynamically optimize the power distribution results, and is difficult to meet the requirements of complex grid structures, resulting in the power being distributed to inappropriate areas of the generators, leading to an increase in the equipment failure rate of hydropower station generators.

[0016] To better understand this application, more detailed descriptions of various aspects of this application will be made with reference to the accompanying drawings.

[0017] To solve the technical problems raised in the background art, this application provides a preferred embodiment: The specific content of this embodiment is as follows: As Figure 1 shown, an AGVC system for small hydropower stations with power distribution considering optimal voltage includes the following specific steps: S1.

Store the collected data in the storage component for use in the analysis process.

[0018] In one implementation manner of the present invention, the data of the vertical height difference of the water flow corresponding to each generator set in the hydropower station is obtained by real-time monitoring of the upper and lower reservoir water level sensors to analyze the energy conversion potential of the water corresponding to each generator set in the hydropower station. The operating state data of each generator set in the hydropower station during operation includes the temperature change data, instantaneous load data, and operating time data of each generator set in the hydropower station during operation.

Obtain the power distribution adjustment ratio index for each generator set at each time point in the hydropower plant based on the power distribution evaluation index results of each generator set in the hydropower plant, and adjust the power distribution of each generator set in the hydropower plant according to the power distribution adjustment ratio index for each generator set at each time point in the hydropower plant.

Among them, the power distribution adjustment ratio index calculation formula for the i-th generator set in the hydropower plant at time point ti is: , where is the average value of the power distribution evaluation index of the generator sets in the hydropower plant, is the power distribution evaluation index of the i-th generator set in the hydropower plant, is the total power demand value of the generator sets in the hydropower plant at time point ti. It should be noted that in this formula obtain the distribution of the power adjustment amount of each generator set in the hydropower plant through the sum of the absolute deviations between the power distribution evaluation index of each generator set in the hydropower plant and the average value of the power distribution evaluation index of the generator sets in the hydropower plant; S42. Arrange the calculated power distribution adjustment ratio index of each generator set at each time point in the hydropower plant in ascending order, and adjust the power distribution ratio of each generator set in the hydropower plant in turn according to the arrangement result of the power distribution adjustment ratio index.
