Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The embodiment of the invention provides a multi-user power distribution management method, a device, a controller and equipment aiming at the problems that in the prior art, a direct-current power supply of each communication base station only supplies power to a load of a user, so that resource waste and equipment utilization rate are caused, so that the same direct-current power supply system can simultaneously supply power to the loads of a plurality of users and can manage the loads independently, the equipment utilization efficiency is improved, and the resource waste is reduced.
Fig. 1 is a schematic diagram illustrating basic steps of a multi-user power distribution management method according to an embodiment of the present invention, wherein the multi-user power distribution management method is applied to a dc power supply system for supplying power to a communication base station. Here, it should be noted that the dc power distribution form of the dc power supply system is a sub-user power distribution form, that is, the dc power supply system directly divides power distribution areas of different users to individually distribute power to each user.
The multi-user power distribution management method provided by the embodiment of the invention specifically comprises the following steps:
Specifically, the power distribution areas of the multiple users are connected in parallel, so that the phenomenon that power cannot be supplied to other users due to the fact that the load of a certain user is abnormal in the process of supplying power to each user is avoided; meanwhile, the load power supply demand of each user is independently and finely managed according to the demands of different customers.
And step 12, acquiring an important power distribution area and a secondary power distribution area of each user power distribution area.
Specifically, each of the user power distribution areas is divided into an important power distribution area and a secondary power distribution area, so that loads of different importance degrees are independently managed according to the importance degree of the load of each user, and the load of the important power distribution area can be supplied with power for a long time when the alternating current is powered off.
And step 13, independently managing the current power distribution condition of each user according to the current power utilization state of each important load and each secondary load in the process of supplying power to the important load accessed to the important power distribution area of each user and the secondary load accessed to the secondary power distribution area of each user.
The user divides the load into two types of important load and secondary load according to the importance degree of the load of the user, accesses the important load to an important power distribution area in the user power distribution area of the user and accesses the secondary load to a secondary power distribution area in the user power distribution area of the user. Specifically, an important power distribution area and a secondary power distribution area in each user power distribution area are two power distribution areas connected in parallel, so that the important load and the secondary load are managed independently.
Specifically, as shown in fig. 3, in step 13, the step of independently managing the current power distribution situation of each user according to the current power consumption state of each important load and each secondary load includes:
and step 131, monitoring the current total electricity consumption of the important load and the secondary load of each user in real time.
And step 132, reporting the current total power consumption of each user to an upper computer or storing the current total power consumption in a memory.
The current power consumption of each user is monitored and stored, so that the user can conveniently inquire the total power consumption of the equipment in a period of time as required, the power consumption proportion of the total power consumption of the load of the user to the total power consumption of the direct-current power supply system in the period of time is facilitated, the user can know the running condition and the power consumption condition of the equipment in the inquired period of time, and a data basis is provided for the improvement, energy conservation and emission reduction of the user equipment.
The total power consumption of each user is reported to the upper computer, so that each user can obtain the current total power consumption of the load in real time, and the power consumption condition and the running condition of the load are analyzed in real time; the total power consumption of each user is stored, so that the user can conveniently inquire the power consumption condition of the load in a required time period at any time, and the requirement of the user on the statistical analysis of the power consumption condition of the load in a long time is met.
When the alternating current for supplying power to the direct current power supply system is powered off, a battery is needed to supply power to the direct current power supply system, so that the power consumption requirement of each user load is met. In the process of supplying power by adopting the battery, the total power consumption of each user is monitored, counted and stored, the running condition and the power consumption condition of the load of the user are known by the user, meanwhile, the standby power capacity of the battery can be accurately calculated, the configuration condition of the existing battery is analyzed and judged, and reference data is provided for selection of the standby power capacity of the battery for supplying power to a newly-built direct-current power supply system in the future, so that the battery resource is more effectively configured, the maximum utilization of the resource is achieved, and the operation cost is reduced.
Step 133, monitoring the current status of the important load and the secondary load of each user in real time, and outputting alarm information if the current status information of the important load or the secondary load does not satisfy the preset condition.
Specifically, the current states of the important load and the secondary load of each user are monitored in real time, so that when any load fails, alarm information corresponding to the fault is output, and the requirement of independently and finely managing the important load and the secondary load of each user is met.
In the process of supplying power to the user load, the current state information of each monitored user generally includes: when any one of the current voltage information, the current information and the current temperature information of the load is not matched with the preset condition, for example, the voltage of the load is greater than a preset voltage value, the current of the load is greater than a preset current value, or the environmental temperature of the load is greater than a preset temperature value, alarm information is output to inform a user that the load is abnormal. Therefore, the daily maintenance and management of the load by a user are facilitated, and the service life of the load is prolonged.
Further, in the multi-user power distribution management method according to the embodiment of the present invention, when the ac power supplied to the dc power supply system is cut off, the method further includes the following steps:
when the direct current power supply system is powered by the battery, the power-down of each important load and each secondary load is controlled according to the current state of the battery. The power-off of each important load and each secondary load is controlled to ensure that the battery is not damaged by over-discharge.
Preferably, the control of the power supply of each important load and each secondary load comprises the following two modes:
the first method is as follows:
and monitoring the current voltage of the battery in real time, and controlling switches connected with the secondary loads to be disconnected when the current voltage of the battery is reduced to a first preset voltage so as to enable the secondary loads to be powered off. Here, the first preset voltage is determined according to a large amount of experimental data, and the voltage value for ensuring that each important load is powered by the battery to work is longer.
And when the current voltage of the battery is reduced to a second preset voltage, the main switch connected with the battery is controlled to be disconnected, so that each important load is powered down. Here, the second preset voltage is a limit voltage of the battery, and when the current voltage of the battery is lower than the second preset voltage, the battery may be discharged excessively, and thus, the battery is required to stop supplying power.
The second method comprises the following steps:
acquiring preset standby power time of a secondary load of each user; the preset equipment power duration is determined by each user according to needs, and when the alternating current is powered off, the preset duration is set for meeting the working duration of important loads and the working duration of the secondary loads.
And acquiring the current power supply time of the battery.
And when the current power supply time length reaches the preset standby power time length of any secondary load, controlling a switch connected with the secondary load to be disconnected so as to enable the secondary load to be powered off. When the current power supply duration is the same as the preset standby power duration of the secondary load, the current working duration of the secondary load is reached, and the secondary load does not need to work continuously according to the parameters set by the user.
And when the current voltage of the battery is reduced to a third preset voltage, a main switch connected with the battery is controlled to be disconnected, so that all loads are powered down. Here, it should be noted that, the important loads of each user are loads used for data transmission, and generally, the important loads are not allowed to stop operating, so that, when the battery can supply power, the important loads all need to operate normally, so that, in the second mode, the condition for powering down each important load is similar to the first mode, and each important load is powered down when the battery reaches the minimum voltage value, and of course, if the current voltage of the battery reaches the third preset voltage, if there is a secondary load of a user still operating, the operation needs to be stopped all together, so that, when the current voltage of the battery reaches the third preset voltage, the main switch connected to the battery is controlled to be turned off.
The process of controlling the power-down of each important load and each secondary load in the first and second manners will be described with reference to fig. 4.
As shown in fig. 4, a schematic diagram of the connection of the user power distribution areas to the battery is provided, wherein the battery 9 is electrically connected to four parallel user power distribution areas through a main switch K5, and each user power distribution area is provided with a switch, that is: a first switch K1 in series with the first secondary distribution area 1, a second switch K2 in series with the second secondary distribution area 2, a third switch K3 in series with the third secondary distribution area 3 and a fourth switch K4 in series with the fourth secondary distribution area 4; specifically, a first important power distribution area 5 connected in parallel across the first secondary power distribution area 1 and the first switch K1 forms a first user power distribution area together with the first secondary power distribution area 1 and the first switch K1; a second important power distribution area 6 connected in parallel across the second secondary power distribution area 2 and the second switch K2, constituting a second user power distribution area with the second secondary power distribution area 2 and the second switch K2; a third secondary power distribution area 7 connected in parallel across the third secondary power distribution area 3 and the third switch K3, and constituting a third user power distribution area with the third secondary power distribution area 3 and the third switch K3; a fourth power distribution area 8 connected in parallel across the fourth power distribution area 4 and the fourth switch K4, and the fourth power distribution area 4 and the fourth switch K4 constitute a fourth user power distribution area.
When the alternating current for supplying power to the direct current power supply system is not cut off, each user power distribution area does not need the battery 9 to supply power, and the main switch 5 connected with the battery 9 is disconnected; the first switch K1, the second switch K2, the third switch K3 and the fourth switch K4 are all closed, and the loads of all users work normally.
When the alternating current for supplying the direct current power supply system is cut off, firstly, whether the important loads and the secondary loads are controlled to be powered down in a first mode or a second mode is determined.
If the major loads and the minor loads are controlled to be powered down in the first way, when the battery 9 supplies power, first, the total switch K5, the first switch K1, the second switch K3, the third switch K3 and the fourth switch K4 connected to the battery 9 are closed to supply power to all the loads of the users.
In the process of supplying power to the battery 9, acquiring the current voltage of the battery 9 in real time, comparing the current voltage with the first preset voltage and the second preset voltage, and controlling the first switch K1, the second switch K2, the third switch K3 and the fourth switch K4 to be switched off when the current voltage is the same as the first preset voltage, so that the battery 9 stops supplying power to the secondary load of each user, and thus, a longer working time is provided for the important load of each user; when the current voltage is smaller than the first preset voltage, the current voltage of the battery 9 is continuously collected in real time and compared with the second preset voltage, if the current voltage is the same as the second preset voltage, the main switch K5 is controlled to be switched off, the battery 9 stops supplying power, the battery 9 is prevented from being damaged due to over discharge, and at the moment, important loads of all users stop working. Obviously, the first preset voltage is greater than the second preset voltage.
If the power-off of each important load and each secondary load is controlled in the second mode, the preset power-standby time length of the secondary load of each user is firstly obtained, for example: when the preset power backup time of the secondary load of the first user is 2h, the preset power backup time of the secondary load of the second user is 5h, the preset power backup time of the secondary load of the third user is 3h, and the preset power backup time of the secondary load of the fourth user is 5h, when the battery 9 starts to supply power to each user, timing is started, and when the timed time reaches 2h, the first switch K1 is controlled to be switched off, and the power supply of the load connected to the first secondary power distribution area 1 is stopped; when the timed time reaches 3h, controlling the third switch K3 to be switched off, and stopping supplying power to the load connected to the third power distribution area 3; when the timing time reaches 5h, controlling the second switch K2 and the fourth switch K4 to be opened simultaneously, and stopping supplying power to the load accessed to the second secondary power distribution area 2 and the load accessed to the fourth secondary power distribution area 4.
When the power supply for the secondary loads of all users is stopped, the current voltage of the battery 9 is acquired in real time, and when the current voltage is the same as a third preset voltage, the main switch K5 is controlled to be switched off, so that the power supply for the battery 9 is stopped.
In the above embodiment, four users are connected to the dc power supply system, but the number of the users is not limited to four, and any number of users within the range of the dc power supply system can be connected to the dc power supply system.
In the embodiment of the invention, the direct-current power supply system is divided into the plurality of user power distribution areas which are connected in parallel, so that the requirement of independently and accurately managing the loads of a plurality of users at the same time is met, no interference exists among the users, the phenomenon that the loads of other users cannot work normally due to the load fault of a certain user is avoided, the purpose that a plurality of users share one direct-current power supply system and can control the direct-current power supply system respectively is realized, the repeated construction of equipment is reduced, and the use efficiency of the equipment is improved. The power distribution area of each user is further divided into an important power distribution area and a secondary power distribution area, so that independent fine control over important loads and secondary loads is achieved, and the purposes of energy conservation and emission reduction are achieved.
