Embodiment
As in figure 2 it is shown, the load main object periodically controlled is the electrical equipment with energy-storage function, such as electricity ice
Case, electric heater etc..By the investigation and analysis to the electrical equipment with energy-storage function, one hour peak of power consumption time period
In, if spatial load forecasting set of time 10～15 minutes, the most do not affect the work purpose of energy storage device, do not affect the body of user
Test.
This utility model has the control method that direct load controls the negative control electric energy meter of function, first by controlled total capacity
Being divided into n group, the time that often group energy storage load needs wheel control to close down within a cycle is τ, then τ=1/n hour.
Controlled total capacity between 19:00～21:00 as a example by the peak of power consumption time period, i.e. had storage in one day by Fig. 2
The electrical equipment of energy function is divided into 6 groups, then be in " unlatching " state (dotted line frame) and " closing down " state (solid box) cell
Time τ is 10min.It follows that often group has the electrical equipment of energy-storage function and has the time of 10min to be in each cycle
Close down state, and can guarantee that every group has the electrical equipment of energy-storage function and closes down time interval front and back between 2 cycles
It it is all 1 hour, it is ensured that when often group has " filling energy " that the electrical equipment of energy-storage function can have abundance between twice closes down
Between.Being electric refrigerator as one of which has the electrical equipment of energy-storage function, one group of electrical equipment with energy-storage function is electric heating
Hydrophone, remaining 4 groups is that other has the electrical equipment of energy-storage function, and the period 1 is 19:00～20:00, and second round is 20:
00～21:00, wherein 19:00～19:10 and 20:00～20:10 electric refrigerator are closed down, and have one hour between closing down for twice
" fill energy " time, it is ensured that the electric refrigerator of user can normally use；Wherein 19:10～19:20 and 20:10～20:20 electric hot water
Device is closed down, and has " filling energy " time of one hour, it is ensured that the electric heater of user can normally use between closing down for twice.
The energy management of this utility model traffic department centrally through communication module jtag interface debugging, in one day
Two peak of power consumption periods of 10:00～12:00 and 19:00～21:00 send 300 control commands, test to ammeter respectively
Sending information to the communication delay of action tripping operation, result is as shown in table 1.Can obtain according to table 1 data, control signal is sent to perform
Average time, at about 5 seconds, is negligible relative to the 10min in the cycle of control.So, the communication of ammeter control signal
Time delay can meet the requirement that direct load controls.
