Description
Technical field
The utility model relates to load control system field, particularly, relates to the maximum demand control system of balance peakload.
Background technology
electricity Demand amount is growing in recent years, and supply of electric power relatively lags behind, especially summer and winter whole nation most area all short of electricity phenomenons serious.In the face of this severe situation, national grid, each place Utilities Electric Co. have carried out the margining electric method of various ways respectively, demand Side Management is exactly effective means wherein, enforcement demand Side Management is conducive to the stability that beautiful jade adds supply of electric power, promote client electricity consumption level, improve electric energy and grid equipment utilance, ordered electric plays an important role as the effective means of demand Side Management.All take a series of ordered electric measure and scheme in each electric company of China, such as summer high temperature maintenance is avoided the peak hour, enterprise has holidays by turns avoids the peak hour, spatial load forecasting keeps away peak, interruptible load etc.
Industrial cousumer is large electricity consumer, and outside the normal condition except major accident, electricity consumption breach makes up by the management of rationing the power supply of industrial cousumer substantially, is the emphasis of power grid enterprises ordered electrics management to enterprise customer's tagmeme of rationing the power supply.
The existing negligence of management to electric power resource, cause the waste of electric power resource, peak times of power consumption electric power supply can not satisfy the demand.
Utility model content
Technical problem to be solved in the utility model is to provide the maximum demand control system of balance peakload, utilizes electric power resource, cause the peak times of power consumption electric power problem that supply falls short of demand with what overcome that existing control system can not be effective and reasonable.
The technical scheme in the invention for solving the above technical problem is: the maximum demand control system of balance peakload, comprise controller, controller is connected with information acquisition system, warning system, described information acquisition system comprises the signal generator be connected with controller, and signal generator is connected to some electric terminals by electricity consumption bus; Described warning system comprise be connected with controller lack working pulse alarm, loss of voltage alarm, overload alarm, hardware fault alarm; Described controller is connected with multifunction instrument; Controller is also connected to computer.The method of existing control electric power mainly relies on summer high temperature to overhaul and avoids the peak hour, enterprise has holidays by turns and avoids the peak hour, spatial load forecasting keeps away peak, interruptible load etc., but along with industrial electricity increases, the short time is avoided the peak hour or rations the power supply in simple utilization may be effectively, but along with the rapid development of economy, the meaning of rationing the power supply is just little, therefore existing control system can not be effective and reasonable utilize electric power resource, cause peak times of power consumption electric power supply falls short of demand, so not only power supply unit wants " rationally " business unit also to want " rationally ", from enterprise's angle, the energy consumption system of Erecting and improving, efficiently, science, reasonably maximizedly utilize electric power, enterprise can not only be made to have electricity available at electrical network " Rush Hour ", business electrical structure can also be optimized, electrical energy saving, scientific utilization of electricity, reduce the energy cost of enterprise, controller of the present utility model specifically refers to PLC, SWP-CA102 model specifically selected by signal generator, multifunction instrument is absolutely necessary element in low-voltage distribution system, multifunction instrument specifically selects PM5680 model, PM5680 reaches the object reducing peakload by fast shut-off associated loadings, in addition, PM5680 can also allow Time And Event be correlated with, be integrated with time-of-week switching function, PM5680 is as a measuring instrument, be arranged in a steel cabinet, also can be used as an independently element, PM5680 is by the load of monitoring electric power system, the situation of transshipping is avoided to occur, this instrument also can be used for measuring and preserving various electric parameter, comprise average current and performance number user terminal by the information of electricity consumption such as voltage, frequency, the signals of telecommunication such as output pulses pass to signal generator by electricity consumption bus, signal generator by signal transmission to controller, controller by signal transmission to multifunction instrument, PM5680 is in the active power pulse receiving its input or the basis of total active power calculated by internal measurement, necessary parameter can be drawn, instrument calculating mean value continuously within the time of setting, instantaneous value, Trend value and compensation power, when there is overload to power upper limit in Meter recognition, can according to the characteristic parameter of the load of specifying, and when considering these data, detect the necessity cutting off this load, object is in this way made to be exactly reduce switching manipulation as much as possible, in order to avoid affect the normal operation of enterprise, and make the power-handling capability preset be met simultaneously, when control system of the present utility model breaks down, its warning system can start corresponding alarm automatic alarm, notify that maintenance personal overhauls, the computer be connected with controller can be real-time the signals collecting of register system, information also stores in order to checking data by the information of signal controlling and alarm lamp, the utility model is calculated with the signal of telecommunication received by PM5680 multifunction instrument, identify, judge whether to cut off load, when not affecting the normal operation of enterprise, Appropriate application electric power resource, avoid the peak times of power consumption electric power problem that supply falls short of demand, thus, what the utility model overcame that existing control system can not be effective and reasonable utilizes electric power resource, cause the peak times of power consumption electric power problem that supply falls short of demand.
Further, described controller is connected to temperature sensor, and the temperature signal sensed is passed to controller by temperature sensor, and controller analysis temperature signal judges whether the heater that unlatching is connected with controller or heat abstractor.Report and submit to controller by Temperature Humidity Sensor acquisition environment temperature, controller carries out the calculating of temperature data and compares, when temperature is lower than set point time, start electro-heat equipment, and can the power of regulation heating device, thus keep whole controller not affected by too low temperature, and when ambient temperature is higher than certain set point, start heat abstractor, and environmentally the height of temperature carrys out the power of adjusting heat dissipation device, electronic component is made to be unlikely to be burned, thus make each electronic devices and components keep more rational working temperature, add the useful life of equipment
Further, controller is connected to Surveillance center by network interface.Surveillance center can monitor the electricity consumption situation of multiple enterprise simultaneously, is conducive to distribution and the management of large regions electric power resource.
Further, computer is connected to LCD display, printer.Thus the data of all inputs or operation can be read by corresponding function key simply, the situation of all input and output and all parameter currents during the trend that can recall in addition calculates
To sum up, the beneficial effects of the utility model are:
