Hydrogen energy power generation system based on filtering of output filter

Abstract

The invention relates to a hydrogen energy power generation system based on filtering of an output filter, which mainly utilizes low-pass filtering function of the output filter (1) to filter the high-frequency harmonic component in rectifier-level voltage so as to provide approximately constant direct current (DC) voltage to a load. The whole hydrogen energy power generation system comprises main components including a polymer hydrogen energy fuel cell (11), an alternating current (AC)-DC circuit (8), a DC-DC circuit (9), a storage battery (6), an intelligent storage battery monitoring module (SBMS) (4), a DC-AC converter (2), a DC-DC converter (3) and a filter (1). The whole hydrogen energy power generation system is capable of effectively reducing harmonic and commutation nicks of a main power supply, and protecting power electronic components of a driving device from the damage caused by the impact of peak current of the main power supply.

[0002] The core of the entire hydrogen power generation system is the polymer hydrogen fuel cell and the hydrogen generator. The hydrogen generator independently developed by the company can react with water to generate high-purity hydrogen, which is used for power generation by the polymer hydrogen fuel cell. This power generation method It is economical and environmentally friendly, but the electric energy converted by the polymer hydrogen fuel cell needs a series of conversions to drive the load, which involves the filtering of the output electric energy

Generally speaking, there are high-order harmonics in the electric energy converted by the polymer hydrogen fuel cell, which cannot provide a nearly constant DC voltage to the load, which has a great impact on the stability of the entire power generation system.

If this voltage instability problem is not solved, the load cannot operate normally, which seriously damages the safety performance of the power generation system
