Embodiment Construction

[0035] Such as figure 1 As shown, the special energy router includes two AC and DC buses: the AC power supply unit is connected to the DC bus through the AC / DC converter, the photovoltaic array is connected to the DC bus through the phase-shifted full bridge 2, and the energy storage unit is connected to the DC bus through the bidirectional DAB converter. The DC bus realizes energy interaction; the AC power supply unit is connected to the AC bus through a bypass switch, and the DC bus realizes energy interaction with the AC bus through a PWM inverter; the AC bus supplies power to three-phase and single-phase AC loads respectively, and the DC bus is phase-shifted The full-bridge converters 3 and 4 respectively supply power to different DC loads, and also have a DC bus connection interface to facilitate system expansion.

[0036] Such as Figure 1~2 As shown, the power supply mode of the energy converter is as follows:

[0037] Mode 1: Light-load or no-load power supply, P Lo...

Abstract

The invention discloses a power supply method for an island special energy router, which belongs to the technical field of electric power control. The energy router includes two buses of AC and DC: the AC power supply unit is connected to the DC bus through the AC / DC converter, the photovoltaic array is connected to the DC bus through the phase-shifted full bridge 1, and the energy storage unit realizes energy interaction with the DC bus through the bidirectional DAB converter The AC power supply unit is connected to the AC bus through the bypass switch, and the DC bus realizes energy interaction with the AC bus through the PWM inverter, and the AC bus supplies power to three-phase AC loads and single-phase AC loads respectively; Combined power supply with the AC power supply unit can effectively improve the acceptance capacity of the wide input voltage range. Under load overload conditions, the present invention uses a PWM inverter and an AC power supply unit to jointly supply power, which can provide two AC energy channels at the same time, effectively improving the overload capacity of the power supply.

Description

technical field [0001] The invention relates to the field of power control, in particular to a power supply method for a sea-island special energy router. Background technique [0002] my country has a vast sea area, long and narrow coastline, numerous islands, and abundant coastal resources. As the outpost of the "Maritime Silk Road" strategy, islands have a special and important position in homeland security and national defense security; the development of islands is a major deployment of my country's "maritime engineering" and is the only way for my country to become a "maritime power". At present, the island's military weapons and equipment, national defense and civilian facilities urgently need stable and reliable power supply. A highly reliable power supply system is the cornerstone and important guarantee for island construction. [0003] The islands have rich reserves of new energy such as solar energy, wind energy, wave energy, and biomass energy. Compared with t...
