In order to realize the function needs of the described automatic power-measuring product of the embodiment of the invention, described functional module 5 specifically can be the module with corresponding function.Described functional module 5 is specifically as follows the load control module, or reactive compensation module, or carrier communication module.
For the ease of those skilled in the art's understanding, specify the concrete function that load control module and reactive compensation module and carrier communication module can realize below.
Load control module (being called for short negative control module), main according to the pre-configured load control information of user, the load condition of circuit is monitored.The major function of load control module comprises: load control, load are analyzed, subscriber's line control and maintainable.
Load control: from allocation list, read user configured load control information, analyze which table and count the control of to load, table meter for each control of need loading, analyze the current load control period that whether is in, if, startup to the load controlling function of this table meter (send message to data processing module, require to finish data processing to this table meter at every turn after, all will work as time instantaneous power value of collection and send to the control module of loading and analyze); Read the load control curve of this period correspondence; Read the finish time of controlling the period when preload.If not, read the initial moment of load control period next time.
Load is analyzed: read the instantaneous power value, compare according to the ultimate value on acquisition time and the load control curve, if the value of overstepping the extreme limit, request alarm/logging modle is handled this incident, otherwise finishes present analysis.
Subscriber's line control: when background server sends the request of tripping operation/combined floodgate, user's circuit is controlled by this module.
Maintainable: module starts back record current version information; Can be according to the current running log of parameter graduation record, the running log grade can be changed and at any time without restart routine; Can write running log journal file or directly output to aiming screen according to parameter.
Reactive compensation module:
Alternating current is in by pure resistance, and electric energy has all changed into heat energy, and in by pure capacitive or pure inductive load, does not do work.That is to say that alternating current does not have consumed power by pure capacitive or pure inductive load the time, be reactive power.Certainly actual loading can not be pure capacitive load or pure inductive load, generally all is the Combination load, electric current just has the part electric energy not do work when passing through like this, is exactly reactive power, the power factor of this moment in order to improve the utilization factor of electric energy, will be carried out reactive-load compensation less than 1.
Electric load in the electrical network such as motor, transformer etc., major part belongs to inductive reactance, and needing in operational process provides corresponding reactive power to these equipment.Install in electrical network after the capacitive apparatus such as shnt capacitor, synchronous capacitor, the part reactive power minor scale power net power supply that can supply with inductive reactance consumption provides reactive power to inductive load.Also promptly reduce reactive power flowing in electrical network, therefore can reduce the electric energy loss of transmission line of electricity, improve the service condition of electrical network because of carrying reactive power to cause.This way is called reactive-load compensation, and the module of specific implementation reactive-load compensation is a reactive compensation module.
Carrier communication module specific implementation power line carrier, PLC.Power line carrier, PLC is to be a kind of carrier communication of transmitting on the electric power transmission line of 50Hz in power frequency.According to the difference of employed coupling scheme, be divided into the combination and the hf channel that combines mutually mutually.It is the hf channel of combination mutually, the hf channel that the common employing of protection special carrier transceiver combines mutually that signal post's employing has carrier communication.The transmission band of power line carrier, PLC is generally 40-500kHz.
The automatic power-measuring product of described replaceable functional module is specifically as follows terminal automatic power-measuring products such as ammeter.
Because the automatic power-measuring product of the described replaceable functional module of the embodiment of the invention is provided with the cavity 101 with reservation shape, and has through hole 102 at cavity 101 base plates in housing; The mainboard of described automatic power-measuring product is arranged between housing base plate and cavity 101 base plates, and can installation function module 5 in described cavity 101, and described functional module 5 specifically can be connected with described mainboard by described through hole 102.Like this, when described automatic power-measuring product need be realized certain function, can be by corresponding functional module be installed in described cavity, and described functional module 5 linked to each other with described mainboard get final product.
The above only is the preferred implementation of the automatic power-measuring product of replaceable functional module of the present invention, does not constitute the qualification to protection domain of the present invention.Any any modification of being done within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present invention.
