Abstract
The utility model discloses an intelligent reactive power compensation system by utilizing a power line carrier communication mode. The intelligent reactive power compensation system comprises reactive power compensators, carriers, a power monitoring system and power lines, wherein the reactive power compensation systems are connected with each other through the power lines and the power monitoring system, and the carriers are disposed inside the reactive power compensators and serve as communication carriers. According to the intelligent reactive power compensation system, the power line carrier technology is utilized as a mode of communication conducted by the reactive power compensators and the power monitoring system, and thus the intelligent reactive power compensation system is safe and reliable.
Description
Technical field
The utility model relates to a kind of intelligent powerless compensation system, particularly relates to a kind of intelligent powerless compensation system that utilizes the power carrier communication mode.
Background technology
Because the develop rapidly of power electronic technology, non-linear electrical load increases day by day, electric power system power factor level decline harmonic is polluted be on the rise.Thereby, have the novel reactive power compensator of avoiding the cubic expression tertiary quintuple harmonics and arrived application widely.
Form by several unit for its reactive power compensator of big-and-middle-sized transformer station, according to the needs of the ruuning situation and the power factor of load, switching reactive compensator in batches.In order better to realize dynamic reactive power compensation in real time, reactive power compensator needs to carry out communication with electric power monitoring system, so that accept the uniform dispatching of electric power monitoring system.The existing communication modes that uses is the RS485 serial communication interface; The shortcoming of this interface is to need to connect with serial port communication line; Fault effects a slice of a communication interface often; A little less than the antijamming capability, and this interface is prone to break down, thus make it the communication reliability reduce influence electric power monitoring system to its supervision with control.
The utility model content
The utility model technical problem to be solved provides a kind of intelligent powerless compensation system that utilizes the power carrier communication mode, and the mode that it utilizes PLC technology to carry out communication as reactive power compensator and electric power monitoring system is safe and reliable.
The utility model solves above-mentioned technical problem through following technical proposals: a kind of intelligent powerless compensation system that utilizes the power carrier communication mode; It is characterized in that; It comprises reactive power compensator, Carrier, electric power monitoring system, power line; Reactive power compensator is connected with electric power monitoring system through power line, and Carrier is installed in the reactive power compensator and as the communication carrier.
The positive progressive effect of the utility model is: the utility model does not need to connect connection in addition, utilizes power line as the communication carrier, and is safe and reliable.The carrier frequency of the utility model can be from selecting between 10KC to 300KC, can be according to actual field situation, as: harmonic pollution degree, reactive power compensator quantity and location distribution.Information summaries such as the attenuation rate of carrier communication are considered its carrier frequency of decision, thereby can effectively avoid interference range, and the reliability of communication is improved greatly.The reactive power compensator of the utility model is connected with electric power monitoring system through power line, and communication signal exchanges through carrier communication mode (Carrier) and electric power monitoring system, does not need other frame communication line, and reliability and communication speed all improve greatly.
Description of drawings
Fig. 1 utilizes the structural representation of the intelligent powerless compensation system of power carrier communication mode for the utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.
As shown in Figure 1; The utility model utilizes the intelligent powerless compensation system of power carrier communication mode to comprise reactive power compensator 1, Carrier 2, electric power monitoring system 3, power line 4; Reactive power compensator 1 is connected with electric power monitoring system 3 through power line 4, and Carrier 2 is installed in the reactive power compensator 1 and as the communication carrier.
The utility model does not need to connect connection in addition, utilizes power line as the communication carrier, and is safe and reliable.The carrier frequency of the utility model can be from selecting between 10KC to 300KC, can be according to actual field situation, as: harmonic pollution degree, reactive power compensator quantity and location distribution.Information summaries such as the attenuation rate of carrier communication are considered its carrier frequency of decision, thereby can effectively avoid interference range, and the reliability of communication is improved greatly.The reactive power compensator of the utility model is connected with electric power monitoring system through power line, and communication signal exchanges through carrier communication mode (Carrier) and electric power monitoring system, does not need other frame communication line, and reliability and communication speed all improve greatly.
The foregoing description is as to the qualification of the utility model, all any modifications of in the scope of the utility model, being done, is equal to replacement, improvement etc., all belongs to the protection range of the utility model.
