In view of the above, the utility model provides a user side power grid peak regulation street lamp assembly, which is used for reasonably scheduling idle resources at the user side and realizing the power grid peak regulation function.
Fig. 1 is a schematic diagram of a peak shaving street lamp assembly of a user side power grid, referring to fig. 1, including a street lamp illuminator 30, a storage battery pack 20, a bidirectional converter 10 and a peak shaving controller 40; the storage battery pack 20 is respectively and electrically connected with the street lamp illuminator 30 and the bidirectional converter 10, and the peak shaver controller 40 is respectively and electrically connected with the storage battery pack 20 and the bidirectional converter 10; the street lamp illuminator 30 comprises an LED illuminator 31 and an illumination start-stop device 32, the LED illuminator 31 is electrically connected with the illumination start-stop device 32, the illumination start-stop device 32 is used for starting the LED illuminator 31 and closing the LED illuminator 31, and an execution device of the illumination start-stop device 32 is a miniature electromagnetic relay or a semiconductor electronic device; the bidirectional converter 10 comprises an internal controller 11 and an external signal input end 12, wherein the internal controller 11 is electrically connected with the storage battery pack 20, and the external signal input end 12 is electrically connected with the peak shaving controller 40; the bi-directional converter 10 further comprises an ac output 13, the ac output 13 being adapted to be connected to a power grid.
Specifically, in the user side power grid peak regulation street lamp assembly 100, the street lamp equipment is adjusted, the storage battery pack 20 and the bidirectional converter 10 are arranged, when peak regulation is needed, the bidirectional converter 10 is converted into an inversion state, electric energy in the storage battery pack 20 is converted into alternating current which is synchronous with a power grid, the alternating current flows out through the alternating current output end 13, and the alternating current is sent into the power grid after the synchronization detection; when peak shaving is not needed, the bidirectional converter 10 is in a rectifying state, and the storage battery pack 20 is charged for energy storage or provides electric energy for the street lamp illuminator 30. The bidirectional converter 10 includes an internal controller 11 and an external signal input 12, and the external signal input 12 is electrically connected to the peak shaver controller 40, and receives a signal transmitted by the peak shaver controller 40, where the signal includes the execution peak shaver information and the execution exit information. By means of the arrangement, the peak regulation of the user side power grid can be achieved through equipment improvement of the street lamps, namely, on the premise that night illumination is normally provided by the street lamps, idle resources of the user side are reasonably scheduled, the function of the peak regulation of the power grid is achieved, the facility change is small, the investment is low, the implementation speed is high, and the power supply pressure of the power grid at the peak of the power consumption load can be effectively relieved.
It should be noted that, after the electric energy in the storage battery pack 20 is converted into ac power and output through the ac power output terminal 13, it is required to perform synchronization detection, that is, to detect whether the output ac power is in synchronization with the power grid, and then send the ac power into the power grid after synchronization with the power grid. The utility model is not particularly limited to the synchronization detection device, and can realize the synchronization detection function. For example, a synchronous detector, a PSS660U digital automatic quasi-synchronous device, an ASYN automatic quasi-synchronous device, etc. can be used.
It should be noted that, when peak shaving is required or peak shaving is not required, the power grid dispatching center sends information to the peak shaving controller 40. The power grid dispatching center monitors the load change dynamic state in real time, automatically displays dynamic curves and automatically gives early warning, synthesizes the urban weather forecast information change curves, selects to enter a peak regulation state or exit the peak regulation state and sends information to the peak regulation controller 40.
Specifically, the present utility model provides an alternative implementation that the grid dispatching center monitors the peak of the power load about to arrive, and selects to enter a peak shaving state, and sends request peak shaving information to the peak shaving controller 40; the peak shaver controller 40 receives the confirmation request peak shaver information and replies to the power grid dispatching center; meanwhile, the peak shaver controller 40 converts the request peak shaver information into the execution peak shaver information which can be accurately executed by the battery pack 20 and the bidirectional converter 10, and transmits the execution peak shaver information to the battery pack 20 and the bidirectional converter 10; after the storage battery pack 20 and the bidirectional converter 10 receive the peak shaving information, the bidirectional converter 10 immediately converts the peak shaving information into an inversion state, converts the electric energy in the storage battery pack 20 into alternating current synchronous with the power grid, and sends the alternating current into the power grid.

After exiting the peak regulation state, when illumination is required in the off-peak period, the bidirectional converter 10 starts a floating charging function in a rectification state to perform floating charging on the storage battery pack 20; during peak power periods, when illumination is required, the storage battery pack 20 provides power for the street lamp illuminator 30, and the bidirectional converter 10 enters an automatic dormancy stage in a rectification state.
It should be noted that, before participating in peak load regulation of the power grid, the storage battery pack 20 only provides electric energy for the street lamp illuminator 30 in the peak power period of the power grid, most of time is idle, and resource waste is caused.
The power grid dispatching center can monitor the load change dynamics in real time, automatically display the dynamic curve and automatically early warn, and synthesize the change curve of the weather forecast information of the city to judge or predict whether the peak regulation state is needed to be entered or the peak regulation state is needed to be exited.

So configured, the thermal overload relay prevents the battery pack 20 from being overcharged or overdischarged, either in a peak-shaving state or in a non-peak-shaving state. The principle of the self-protection function of the storage battery pack is that the thermal overload relay is connected in series in a discharge loop of the storage battery pack, and the storage battery pack has low resistance property and negligible influence on charging and discharging when normal current passes through the storage battery pack; when the current is increased to exceed the upper limit, the thermal overload relay immediately heats to present high resistance, the current is limited, namely the power is limited, if the current is further increased under the extreme conditions of short circuit and the like, the circuit is immediately disconnected, and the self-protection function of the storage battery pack is realized.
It should be noted that, the self-protection function of the storage battery pack can also be realized by using the power transistor and the current sensor, the power transistor is in a conducting state under the normal working condition, when the current passing through the power transistor exceeds the upper limit, the current sensor signal is processed, wherein the signal processing operation comprises the steps that the signal passes through a filter, an amplifier, a comparator and other circuits to generate a cut-off voltage signal to be transmitted to the power transistor, the power transistor is changed into a cut-off state from the conducting state, and no current is output, thus the storage battery pack is protected.
