Description

Technical Field

[0001] The present invention relates to the field of power grid technology, and in particular to a method, device and computer equipment for operating a stacked optical microgrid applied to a communication station. Background Art Communication power supply is the key infrastructure of the communication network in the communication bureau station. It is a complete and irreplaceable independent profession in the communication network. At present, the photovoltaic power generation modes used more frequently in the communication bureau station are AC grid-connected power generation and DC off-grid power generation. Among them, AC grid-connected power generation is a photovoltaic power generation system that converts DC power into AC power through an inverter to provide reliable power support for various electrical equipment; DC off-grid power generation is a power generation system that uses DC power supply and self-use. On the basis of the existing communication room power supply system, a photovoltaic power generation system is added to provide power for the network equipment in the room.

[0002] The above-mentioned power supply mode is applicable to the communication bureau station. As the power of photovoltaic components becomes larger and larger, the output of most photovoltaic power modules is 50A at present, which cannot meet the increasing power generation power of a single group. Therefore, there are multiple control modules in the prior art to replace large-size transmission cables, which are used to transmit and regulate the power transmission of a single photovoltaic system separately. However, in common photovoltaic projects in communication rooms, the self-control, protection and management capabilities of the entire photovoltaic power generation system are poor, and the power configuration and power distribution cannot be flexibly adjusted according to actual power demand. When the connection between the solar photovoltaic array and the corresponding controller is broken, the entire photovoltaic power generation system will lose the energy transmission of the corresponding array, resulting in waste of resources and high maintenance costs.

[0018] Specific real-time method The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: See also Figure 1 The present invention provides a technical solution: a method for operating a stacked optical microgrid applied to a communication station, comprising: Step S1, obtaining a first critical power value of real-time power generation of a solar common source array end; In order to ensure the data transmission requirements of the operation method, before step S1, it also includes: Step S01, obtaining the address of each power module in the solar controller; Step S02, pre-store multiple groups of graded power values ​​entered by the user and a power execution plan that matches the graded power values ​​one-to-one, the power execution plan includes multiple working states, each working state corresponds to an execution power, and the execution power is realized by combining multiple groups of power modules with different addresses with each other or operating them individually, so that the operating number of multiple groups of power modules affects the execution power.

[0020] Step S2, adjusting the power execution plan according to the first critical power value; The above step S2 adjusts the power execution scheme according to the first critical power value, including: Comparing the first critical power value with a plurality of preset groups of the classified power values, and when a group of the classified power values ​​having the smallest difference with the first critical power value is screened out, marking the screened out classified power values ​​as real-time power values; Acquire the power execution scheme matching the real-time power value according to the real-time power value; The solar controller is regulated according to the power execution scheme.

[0021] Step S3, confirming a second critical power value of the real-time power storage amount of the energy storage end according to the power execution scheme and the first critical power value; Step S4, obtaining a third critical power value of the historical power storage amount of the energy storage end; Step S5, obtaining a fourth critical power value of the real-time power consumption of the grid-connected terminal; Step S6, adjusting the real-time grid configuration according to the second critical power value, the third critical power value and the fourth critical power value.

[0022] In the above step S6, in which the real-time grid configuration is adjusted according to the second critical power value, the third critical power value and the fourth critical power value, the real-time grid configuration includes at least two grid power supply states, one is that the mains end alone or the mains end and the energy storage end jointly supply power to the communication load end, and the other is that the energy storage end alone supplies power to the communication load end, and the step S6 includes: Obtaining a calculated value of the sum of the second critical power value and the third critical power value minus the fourth critical power value; Determine whether the calculated value is a negative number: When it is confirmed that the calculated value is a negative number, adjusting the mains terminal alone or the mains terminal and the energy storage terminal to supply power to the communication load terminal; When it is confirmed that the calculated value is a positive number or zero, the energy storage end is adjusted to supply power to the communication load alone.

[0023] It should be understood that the second critical power value indicates the amount of electricity that can actually be stored in the energy storage terminal, the third critical power value indicates the amount of electricity already stored in the energy storage terminal, and the fourth critical power value indicates the amount of electricity that the communication station needs to use in real time; The sum of the second critical power value and the third critical power value is compared with the fourth critical power value. Based on the principle of stable power consumption, when the difference between the two is zero or a positive number, the real-time grid configuration is adjusted to power the energy storage end. At this time, the energy storage end is in a state of charging and discharging at the same time; when the difference is a negative number, the real-time grid configuration is adjusted to power the mains end. At this time, the energy storage end only stores electricity and does not discharge. This can effectively avoid the problem of empty discharge of the energy storage end, which affects the energy storage effect and the service life of the energy storage end, and can also effectively maintain the power consumption stability of the communication station; Or when the difference is a negative number, the stable time point at which the energy storage end can supply power is calculated, that is, the time threshold at which the historical stored power in the energy storage end can supply power stably. When the power supply of the energy storage end reaches a stable time point, it is set to switch to the mains power supply and stop the discharge of the energy storage end. That is, the mains power end and the energy storage end are powered synchronously. At this time, after the energy storage end discharges for a period of time, the discharge interface is automatically closed and only charging operations are performed to effectively avoid over-discharge of the energy storage end and affect the service life and energy efficiency of the energy storage end.

The structural power transmission route is used to realize that among multiple groups of power modules, the number of power modules that need to be connected can be adjusted according to the total input, which is more flexible and stable to use; On the other hand, it also effectively achieves the purpose of the power controller effectively regulating the final power supply solution.
