Before, motor driving system actually consign during generating set normal operation is influenceed due to sudden load change, influence motor and
The service efficiency of generating set and life-span.Therefore, how the impact load problem of generating set is avoided to be the ultracapacitor
It is extremely urgent at present.
The content of the invention
The present invention be exactly in view of the deficienciess of the prior art, provide a kind of ultracapacitor impact load compensation system,
Realize and charged to ultracapacitor, when ultracapacitor can carry out work(in time when impact load occurs for generating set
When rate compensates, ensure to electric machine with energy, meet actual operation requirements.
To solve the above problems, the technical solution used in the present invention is as follows：
A kind of ultracapacitor impact load compensation system, including generating set and ultracapacitor, electricity on the generating set
