Problems solved by technology

The load connected at any time may cause the power source to be overloaded, cause the voltage to drop and affect the normal operation of other loads, and may also cause the fuse to operate, resulting in short-term failure of the power system
The existing open-loop transmission characteristics of the power system determine that the above-mentioned faults cannot be avoided from the source

Embodiment Construction

[0025] Figure 1 is a schematic diagram of a digital power interface. The digital power interface includes a plug and a socket, and its power part is the same as a general power plug connector. The difference is that the grounding port is changed to an interface similar to a USB. The interface includes a digital plug 1 and a digital socket 2. The outside of the plug is a metal frame, connected to the ground, and there are two reeds inside; the inside of the socket also has two reeds. When the plug is inserted into the socket, the reeds contact each other. The digital power interface is a channel for power and information transfer.

[0026] Figure 2 is a schematic diagram of a digital power transfer carrier, the carrier structure is an outer insulating layer 4 wrapping two power cables 3 and a shielded twisted pair 6, the outer periphery of the two cables is wrapped by an inner insulating layer 5, double The periphery of the twisted wires is wrapped by the grounded shielding lay...

Abstract

The invention relates to a digitized allocation method of an electrical power transmission system of digital distribution methods. The method establishes a digital power transmission system, the system including a digital power source, a digital power splitter and a digital load, wherein firstly the digital power source outputs a power limit based on the design capacity limit; the digital power splitter limits the allocation power limits based on the designed capacity; and the applied power of the digital load can electrify after the approval of the distributor. The method can predict the load actioin to avoid the occurence of the overloading in the power system, so as to make the power system more stable.

Description

technical field [0001] The invention relates to a distribution method of an electric power transmission system, in particular to a digital distribution method. Background technique [0002] The transfer carrier in the existing electric power system (hereinafter referred to as the power system) is a single power transfer carrier. Due to the complexity of the impedance characteristics of the power carrier, it is difficult to perform reliable data exchange. Therefore, the power system is determined to be an open-loop, Unpredictable and unreliable systems. In order to monitor the system, an additional data communication network and a large number of sensing devices need to be established, which is expensive. [0003] In an open-loop power transfer system, loads can be switched in and out at any time. The power source cannot know the power output value of the next step, and can only be predicted based on empirical values, so precise control cannot be performed. In a sense, the...
