The UPS power supply number connected with the surface of the multi-power supply load is n, the number n is more than or equal to two, the UPS power supply number connected with the surface of the multi-power supply load is generally set to 2, so that the multi-power supply load can simultaneously and averagely draw power from two UPS power supplies, when one side is interrupted, the other side provides the power required by all the multi-power supply loads, when the bidirectional multi-power supply load is generally used, a small number of multi-power supply loads are generally used, for example, the number of the multi-power supply loads is within 50, and the like, when more than 50 multi-power supply loads are adopted, three groups, four groups and other UPS power supply structures can be arranged on the surface of one multi-power supply load, when one UPS power supply is interrupted, the rest multiple UPS power supplies simultaneously to the multi-power supply loads which are commonly loaded with the damaged power supplies, and therefore the fluctuation of the UPS power supply is reduced, and the stability is higher.
The power supply system equipment at UPS place includes the UPS, the switch board, many power loads, interconnecting link and mains supply, equipment among the entire system all can be set for according to the used equipment structure of the power supply that has corresponding now, except UPS, the switch board, many power loads, interconnecting link and mains supply, still include equipment such as circuit fixer, UPS mount, under the prerequisite that satisfies the connection structure of each equipment of entire system, internal device among the power supply system is not limited to above-mentioned several kinds, can set for according to actual equipment installation condition.
The second embodiment is as follows:
as shown in fig. 1-5, the UPS power supply in the whole power supply system generally adopts the existing UPS power supply, and the specific operation mode is that when the mains supply is input normally, the UPS power supply stabilizes the mains supply and supplies it to the load, at this time, the UPS power supply is an ac mains supply voltage stabilizer, and at the same time, it also charges the built-in battery, and when the mains supply is interrupted, the UPS power supply immediately supplies 220V ac power to the load by means of inversion conversion, so that the load keeps normal operation and protects the load from damage to the soft and hard hardware, and the UPS power supply generally provides protection for the over-voltage and the over-low voltage.
The third concrete embodiment:
as shown in fig. 1, in an actual application of the entire system, if the surface of the multi-power-supply load adopts bidirectional power supply, in a manner that the power supply system supplies power to the four-bus UPS power supply, the UPS power supplies of the four buses are set to A, B, C and D in sequence, the serial numbers of the connected multi-power-supply loads are 1, 2, 3, 4, 5 and 6, the multi-power-supply load of the a-UPS power supply connection is set to 1, 4 and 5, the multi-power-supply load of the B-UPS power supply connection is set to 1, 2 and 6, the multi-power-supply load of the C-UPS power supply connection is set to 2, 3 and 4, and the multi-power-supply load of the D-UPS power supply connection is set to 3, 5 and 6, in a manner that the surface of the multi-power-supply load adopts a bidirectional power supply manner, after the UPS power supplies of the four buses are connected to an external mains supply, the six multi-power-supply loads are supplied through the power distribution cabinet for use, at this time, each UPS power supply reaches a maximum load, and when a specific load is calculated, a numerical value is substituted according to a relation in the relationship among the number of the above-supply system, as follows:
because a four-bus UPS power supply connection mode is set, the number of UPS power supplies is N =4, and the power requirement of each multi-power supply load is set to be M =200KW;
the number of the corresponding power distribution cabinets is N =4;
the number of the multiple power supply loads connected to the surface of each UPS power supply is N-1=4-1=3;
the total quantity of the multiple power loads in the whole power supply system is N (N-1)/2=4 (4-1)/2=6;
the total power supply capacity of the UPS in the whole power supply system during stable operation is MN (N-1)/2 =200KW multiplied by 4 (4-1)/2 =1200KW, and the power supply capacity corresponding to a single UPS is M (N-1)/2 =200KW (4-1)/2 =300KW;
the maximum power supply capacity of the UPS is MN/2=400KW;
the utilization rate of the capacitance of the UPS power supply is (N-1/N) 100% = (4-1/4) × 100% =75%;
when the connection of four buses is obtained, the maximum load rate of the UPS is 75 percent;
according to the data of the four-bus UPS power supply obtained above, when the UPS power supply terminal in a specific system is interrupted, for example, under normal conditions, each group of UPS power supply carries 3 groups of loads, and bears half of the power requirement, namely 300kW, the utilization rate of the UPS power supply is 75%, if the A-UPS power supply exits the system, the B-UPS power supply bears the whole requirement of the No. 1 multi-power supply load, bears the half of the No. 2 multi-power supply load and the No. 6 multi-power supply load, the total is 400kW, the C-UPS power supply and the D-UPS power supply are similar, each bear 400kW power requirement, the capacity can meet the requirement, for example, when the B-UPS power supply is interrupted, the C-UPS power supply bears the whole power requirement of the No. 2 multi-power supply load, the A-UPS power supply bears the multi-power supply load 1 of the load under the condition that the B-UPS power supply is not available, the centralized power supply of the No. 1 multi-power-source load is independently carried out by the A-UPS, after the No. 6 multi-power-source load commonly loaded by the D-UPS and the B-UPS is interrupted by the B-UPS, the power supply of the No. 6 multi-power-source load of the D-UPS load is completely supplied, the multi-power-source loads with other serial numbers normally operate, when the B-UPS is interrupted, the power supply quantity in the whole system is less than 300KW for supplying power to the B-UPS, at the moment, the power supply quantities of the A-UPS, the C-UPS and the D-UPS are increased to the maximum 400KW from 300KW, the sum of the increased 100KW load quantities of each UPS just meets the 300KW of the B-UPS loss, and the power supply requirement of the multi-power-source load of the whole power supply system is met.
The fourth concrete embodiment:
as shown in fig. 1, fig. 3, fig. 4, and fig. 5, for the example connection situation of the multi-power supply load of the third embodiment, experimental comparison is performed by replacing the redundant power supply modes of the three existing UPS power supplies, and the comparison shows that the redundant power supply mode of the multi-Bus multi-power supply load in the present application has a significant improvement on the load utilization rate of the UPS power supplies, and the three existing modes are "1+1" dual-Bus parallel redundant power supply, three-Bus parallel redundant power supply, and latch Bus power supply mode, respectively, which are as follows:
the connection quantity of the multiple power supply loads is still set to be 6, and the power supply quantity required by each multiple power supply load is 200KW;
when the two UPS power supplies are connected, the two UPS power supplies are used in parallel, a power supply system of the two complete UPS power supplies needs to be arranged, the cost is high, the power supply quantity of 6 multi-power-supply loads is provided through one complete UPS power supply, each of the two UPS power supplies at least has 1200KW power supply capacity, the maximum internal load utilization rate of the power supply can be 100%, namely 1200KW, the other UPS power supply is used as a standby power supply and keeps a silent state, namely 0KW, after the UPS power supply is damaged, the load in the other UPS power supply spans from 0% to 100% at most, namely 1200KW load sudden change, although the utilization rate is increased, the load sudden change quantity is greatly increased, when the two UPS power supplies are switched, the extremely high pulse impact rate is easily generated, when the UPS power supplies are used for a magnetic disk, a database and the like, the UPS power supplies power through two parallel connection of two UPS power supplies working at the same time, when the fault occurs, the load sudden change value is reduced to 600KW, and the electrophoresis pulse impact is still large;
when three buses are connected, similar to the four-bus connection mode in the third embodiment, three UPS power supplies are arranged to supply power to 6 multi-power loads, after one UPS power supply is interrupted, the other two UPSs need to bear all power loads, at the moment, only three power supply electric quantities are required to be set to be 600KW by the corresponding UPS power supplies, when one UPS is damaged, the other two UPS power supplies need to meet the total power supply electric quantity, the load utilization rate is 66.6%, and the load sudden change value is 200KW, so that compared with the four-bus connection mode, the capacity of the used UPS power supplies is increased, the initial cost is increased, the sudden change value is increased, and the load utilization rate is still insufficient;
the Catcher Bus power supply mode is that N UPS supplies power as a main use, one UPS power supply serves as a standby use, when any 1 UPS power supply fails, a static transfer switch is switched into a standby UPS power supply, the load rate of the power supply scheme is improved to be close to 75%, but the standby UPS power supply is suddenly started when the power supply fails, namely, the current is suddenly changed from 0 to 100%, the standby UPS needs strong loading capacity, even short-time overload is caused, the requirement on the quality of the UPS is high, a large amount of STS equipment is used in the Catcher Bus scheme, the equipment investment is additionally increased, the system complexity is increased, and the reliability is reduced;
through above-mentioned contrast experiment, the many power supply load power supply modes of redundant formula of many generating lines UPS power in this application compare and have load utilization rate height, with low costs, the reliability is high, the sudden change value is little, stability advantage such as strong in current power supply mode.
The fifth concrete embodiment:
