Problems solved by technology

If the power dispatching system cannot be effectively controlled and there is an imbalance between supply and demand, it may cause a wide range of accidents in the system
[0003] In the prior art, the power dispatching system generally converts direct current and alternating current directly. If it is necessary to output multiple levels of direct current and alternating current, it needs to perform multiple step-up and down-stepping, voltage stabilization and inversion, resulting in low energy efficiency of the system power supply. Secondly, , when a certain line fails, the line cannot be switched in time, which may cause the entire power dispatching system to be paralyzed, and the system redundancy is poor, which seriously affects the power distribution work

Abstract

The invention provides a power dispatching system. The AC switching matrix and the DC switching matrix are connected through a rectification unit and an inverter unit, which can convert AC power to DC power and DC power to AC power in real time. When it is necessary to output multiple different DC power and AC power, directly convert The AC power is delivered to the AC load, and the DC power is directly delivered to the DC load, thereby reducing unnecessary rectification and inverter times; at the same time, the detection unit detects the voltage, current, voltage difference and other power attributes on the line and feeds back to the management controller for management and control. The system evaluates the power usage of multiple transmission sources and multiple loads. When a fault point is found, the management controller can switch the power supply line by controlling the switching unit, which can isolate the fault point in time, isolate the fault circuit, improve system redundancy, provide self-healing ability, provide protection for other parts, and reduce the maintenance time It is greatly shortened, and scheduling is set among multiple inputs to improve the efficiency and reliability of the entire power grid.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a power supply dispatching system. Background technique [0002] The power dispatching system is mainly used to solve the power dispatching problem under multiple power sources. It is a complex dynamic system, and its safe and stable operation essentially requires a balance between power generation and load demand at all times. If the power dispatching system cannot be effectively controlled and there is an imbalance between supply and demand, it may cause a wide range of accidents in the system. [0003] In the prior art, the power dispatching system generally converts direct current and alternating current directly. If it is necessary to output multiple levels of direct current and alternating current, it needs to perform multiple step-up and down-stepping, voltage stabilization and inversion, resulting in low energy efficiency of the system power supply. Secondly, , Wh...
