Problems solved by technology

We can imagine that if the 220V supply of electricity for residents is still in accordance with the national regulations, although the normal operation of household appliances can be realized, this will inevitably increase unnecessary power consumption of household appliances, and the 220V voltage connected to household appliances has serious problems. Security risks

Embodiment 1

[0052] Please refer to the attached figure 1 , which shows the flow of the voltage control method of the solar power generation system provided by Embodiment 1 of the present invention.

[0053] figure 1 The process shown includes:

[0054] S101. Obtain the required power voltage of the user.

[0055] In the process of users using electricity, different user families use different types of household appliances with different working voltages, which will lead to different voltages required by users. Therefore, in order to reduce the power consumption of users and meet their needs Requirements, it is necessary to obtain the required power voltage of the user.

[0056] S102. Determine whether the required power voltage is less than 220V.

[0057] Under normal circumstances, it is judged whether the required electricity voltage of the user is less than 220V, if it is greater than 220V, according to the electricity demand of ordinary residents stipulated by the state, the stand...

Embodiment 2

[0062] Please refer to the attached figure 2 , which shows the flow of the voltage control method of the solar power generation system provided by Embodiment 2 of the present invention.

[0063] figure 2 In the process shown, obtaining the required power voltage of the user includes:

[0064] S201. Divide a time period according to the peak power consumption level of the user.

[0065] In the actual power consumption process of the user, the same user has different power consumption peaks in different time periods. For example, during the day, the user consumes more power. Even in the daytime, the power consumption peak value is different in different time periods. Relatively speaking, people sleep most of the time at night, and the peak power consumption at night is relatively small. Therefore, the time period can be divided according to the peak power consumption level of the user.

[0066] S202. Record the time-period power consumption voltage of the user in each time...

Embodiment 3

[0075] Please refer to the attached image 3 , which shows the flow of the voltage control method of the solar power generation system provided by Embodiment 3 of the present invention.

[0076] image 3 In the process shown, obtaining the required power voltage of the user includes:

[0077] S301. Detect the working voltage of each electrical equipment of the user within a set time period.

[0078] In the process of using electricity, each user will be involved in the use of electrical equipment with different working voltages to varying degrees. In the process of working with multiple electrical equipment, the user's required power voltage depends on the working voltage. highest value.

[0079] S302. Taking the highest value of the multiple detected operating voltages as the required operating voltage of the user.

[0080] In the voltage control method of the solar power generation system provided in the third embodiment of the present invention, a specific method of obt...

Abstract

The invention provides a voltage control method for a solar power generation system. The method comprises the following steps: acquiring needed utilization voltage of a user; judging whether the needed utilization voltage is smaller than 220V or not; if a judgment result is positive, regulating voltage delivered to the user by the solar power generation system to the needed utilization voltage; and if the judgment result is negative, regulating the voltage delivered to the user by the solar power generation system to 220V. Through the method, the voltage of solar power generation can be regulated according to the demand of the user, and the voltage is regulated to the needed utilization voltage when the needed utilization voltage of the user is smaller than 220V, so that the power utilization safety is enhanced, and meanwhile the electric energy consumption is lowered. The invention further provides a voltage control system for the solar power generation system.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a voltage control method and system for a solar power generation system. Background technique [0002] Solar energy is an inexhaustible clean energy. Solar energy is more and more favored by people because of its clean, renewable, and abundant resources. Among many fields of solar energy utilization, the field of solar power generation develops most rapidly, and the technology of solar power generation is most widely used. [0003] Although solar power generation technology is developing rapidly, solar power generation is still used as an auxiliary power supply system for thermal power generation systems, especially at this stage, solar power generation is mainly used for residents' lives. We know that in the current power transmission process, since power production and power consumption are usually not located in the same area, long-distance power transmission ...
