Intelligent multi-stage backup uninterrupted power van and operation method thereof

Abstract

The invention discloses an intelligent multi-stage backup uninterrupted power van and an operation method thereof. The van is composed of a chassis, a carriage, a generator set, static changeover switches, a storage battery pack, a rectifier, an inverter, a transducer and a control system. The generator set and the first-stage static changeover switch form a first-stage backup power supply. A selective switch, the storage battery pack, a first-stage circuit breaker, the rectifier, the inverter, a second-stage circuit breaker and the second-stage static changeover switch form a second-stage backup power supply. An intelligent control system is adopted as the control system, a high-speed CAN bus monitoring system is adopted, and a load power, power factor and environment air temperature real-time detecting device is arranged. The switching between the first-stage backup power supply and the second-stage backup power supply is controlled. Host and backup circuits and switching conditions can be automatically and reasonably selected; uninterrupted electricity maintenance for large power loads is achieved through a small-capacity storage battery inversion device, and the conflict between the vehicle-mounting difficulty of a large-capacity conventional UPS power supply system and the large-power tendency of electricity maintenance requirement is remarkably eliminated.

Description

technical field [0001] The invention relates to a power generation equipment, in particular to an intelligent multi-stage backup uninterruptible power supply vehicle. The invention also relates to the operation method of the intelligent multi-stage backup uninterruptible power supply vehicle. Background technique [0002] The electric power industry divides power supply loads into ABC three grades according to their importance. Class A involves life safety and major political, economic and social significance, Class B involves more important political, economic and social significance, and the rest is Class C. Class AB important loads (hereinafter referred to as important loads) generally do not allow power supply interruptions, that is, when the main line of the mains power fails and the power is cut off, the backup power supply should immediately replace the power supply. The power supply guarantee activities for loads are called power guarantee for short. [0003] Accor...
