Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of dual - power supply, and in particular to an intelligent load unloading and loading method and device for dual - power loads. Background Art
[0002] Dual - power load unloading refers to the operation of sending an unloading signal to unload a part of the load before the dual - power supply switches to the standby power supply when the normal power supply fails, considering the possible insufficient capacity of the standby power supply. Power load loading refers to the operation of sending a loading signal to reload the previously unloaded load after the normal power supply resumes normal and the dual - power supply returns to the normal power supply. Currently, the action logics of unloading and loading are fixed and cannot be adjusted according to the on - site electricity demand. With the entry of large - capacity electrical equipment such as charging piles into residential communities, the total electricity consumption capacity during peak periods is greater than the maximum capacity of the community transformer. At this time, even if the power supply does not fail, equipment such as charging piles should be unloaded to ensure the safety of residential electricity consumption. When it is at the low - electricity - consumption trough, the charging piles should be loaded in a timely manner to achieve intelligent management of the load. Summary of the Invention

[0039] Currently, the action logics of unloading and loading are fixed and cannot be adjusted according to the on - site electricity demand. With the entry of large - capacity electrical equipment such as charging piles into residential communities, the total electricity capacity during peak periods has exceeded the maximum capacity of the community transformer. At this time, even if the power supply does not fail, equipment such as charging piles should be unloaded to ensure the safety of residential electricity.

Based on this, a dual - power load intelligent unloading and loading method provided by an embodiment of the present invention can perform intelligent management of the load, intelligently load and unload the load during peak electricity consumption periods, and improve the safety of electricity use.
[0040] For the convenience of understanding this embodiment, first, a dual - power load intelligent unloading and loading method disclosed in an embodiment of the present invention will be introduced in detail.
[0041] Embodiment 1:
[0042] AsFigure 1 As shown in Figure 1 , Embodiment 1 of the present invention provides a method for intelligent unloading and loading of dual - power loads, which specifically includes the following steps:

[0045] Based on the load status, determine whether the loading time of Load 1 or the loading time of Load 2 is greater than the load switching time;
[0046] If so, based on the current status of the secondary load, determine whether Load 1 is in the loading state.
[0047] Preferably, after the step of determining whether Load 1 is in the loading state based on the current status of the secondary load, the method includes:
[0048] If so, based on the total time of the secondary load, determine whether the total time of Load 1 is greater than the total time of Load 2;
[0049] If not, based on the total time of the secondary load, determine whether the total time of Load 2 is greater than the total time of Load 1.
[0050] Preferably, after the step of determining whether the total time of Load 1 is greater than the total time of Load 2 based on the total time of the secondary load, the method includes:.

[0063] If the load factor is less than the load 1 loading threshold load factor, and the delay time is greater than the load 1 load loading time L<EEC2,T>EET2, then it is converted from the original state to load 1 loading and load 2 loading( Figure 2 in state 1).
[0064] Preferably, if load 1 is in the unloading state and load 2 is in the unloading state (i.e., Figure 2 in state 3)
[0065] When the load factor is less than the load 2 loading threshold load factor, and the delay time is greater than the load 2 load loading time, then it is converted from load 1 unloading and load 2 unloading to load 1 unloading and load 2 loading or load 1 loading and load 2 unloading( Figure 2 in state 2 or state 4).
[0066] In summary, Embodiment 1 provides the conversion conditions between states 2 and 4, and Embodiment 2 provides the conversion conditions between the remaining states.
