The influence run to power network and user is also increasingly important.With installed capacity of wind-driven power continuous increase and wind generating technology it is fast
Speed development, the degree of the interaction between wind power plant and power system is further deepened, scope further expands.Wind-electricity integration is given
We bring operation while economic benefit also to power network to bring some negative effects.In the electric power that wind-electricity integration proportion is larger
In system, because Power Output for Wind Power Field has incomplete controllability and expected property, to a certain extent to the wattful power of power network
Rate balance, frequency stabilization generate adverse effect.When wind-electricity integration is run, particularly the minor scale power net of independent operating, power network are built
If relatively weak, network re-active power regulating power is smaller, and the mains frequency stability problem that wind-electricity integration is brought is more obvious.
Therefore, when system frequency changes, if Wind turbines can provide fast and effectively frequency response for power network
Support, backup service can be provided as conventional power plant, then large-scale wind power unit accesses power network, will certainly substitute portion
Divide conventional synchronous generating set.
When primary frequency modulation refers to set grid-connection operation, by external load influence of change, mains frequency changes, at this moment,
The regulating system of unit participates in adjustment effect, changes the load of unit institute band, is allowed to balance each other with external load.It is meanwhile also most
Power reduces the change of mains frequency, and this process is primary frequency modulation.
In order to which fast and effeciently system frequency caused by regulating system imbalance changes, it is necessary to Wind turbines is possessed class
Frequency response and the frequency modulation control ability of Synchronous generator are similar to, at this moment the Primary frequency control ability of Wind turbines becomes heavy to closing
Will.Usually require that conventional power generation usage unit provides certain spinning reserve for Wind turbines, so as to suppress the fluctuation of wind power.But
With the increase of wind-powered electricity generation capacity, spare capacity also increases therewith, will be big if only providing spinning reserve by conventional power generation usage unit
Increase the cost of adding system, and can not still realize that Wind turbines participate in the purpose of system frequency modulation.
Therefore, in no any additional energy-storage system, it is contemplated that utilize the active power controller of Wind turbines itself
To adjust its active power output, so as to participate in the frequency-modulating process of system together with the synchronous motor in system, lifting system entirety
Fm capacity.To ensure participation power system frequency modulation control after large-scale wind power access, the power supply quality of load end subscriber is ensured
