Method, it is characterised in that：The generated energy management intelligent body analysis received in data and analytical procedure S2 is calculated optimal
Power generation is as follows with electricity consumption configuration-direct：
S1：Dynamic rated generation pattern switching wind speed valve point is calculated firstWherein VN sends out for switching magnetic-resistance wind-force
The rated generation wind speed of motor (1)；And expected electricity consumption total power consumption Pc=PL+IBfUBf；
S2：Then judged according to Vw, VT, Pe, Pc and SOC, form optimal power generation and electricity consumption configuration-direct, determination strategy
Including：
1：Work as Vw>VT and Pe>When Pc：Switching magnetic-resistance wind-driven generator is switched to load power tracing control mode operation, it is expected that
Generated output Pg=Pc simultaneously switches off the discharge loop switch KBo of accumulator；
2：Work as Vw>VT and when Pe≤Pc：Switching magnetic-resistance wind-driven generator is switched to power limitation control mode operation, it is expected that the work(that generates electricity
Rated power when rate Pg=kFPEN, wherein PEN are switching magnetic-resistance wind-driven generator normal state, is closed at putting for accumulator
Electrical circuit switch KBo, until the SOC of accumulator<0.2；
3：As Vw≤VT and Pe>When Pc：Switching magnetic-resistance wind-driven generator is switched to load power tracing control mode operation, it is expected that
Generated output Pg=Pc；Meanwhile disconnecting the discharge loop switch KBo of accumulator；
4：As Vw≤VT and Pe≤Pc：Switching magnetic-resistance wind-driven generator is switched to the operation of maximal power tracing control model, phase
Hope generated output Pg=Pa；Meanwhile it being closed the discharge loop switch KBo of accumulator, until the SOC of accumulator<0.2；
And the charge circuit switch KBi of accumulator is closed in strategy 1,2,3 and 4 always, until the SOC=1 of accumulator；Always
The circuit fling-cut switch KL of closed load access；Until the SOC of accumulator<0.2.
9. a kind of controlling party of switching magnetic-resistance wind power generating set multiple agent energy management apparatus according to claim 5
Method, it is characterised in that：The hair electricity executes the power generation of intelligent body driving malfunction, and mutually normally closed corresponding to number collection Z { zi } is controllably opened
(104) are closed to disconnect.
