Drone is called for short " unmanned plane ", is the not manned aircraft utilizing radio robot to handle with the presetting apparatus provided for oneself.Unmanned plane is widely used in the industries such as police, city management, agricultural, geology, meteorology, electric power, rescue and relief work, video capture.From the modern rural area of power-assisted to giving power smart city, all will there be the one seat of unmanned plane in the place of the aerial solution of every needs.Along with unmanned plane range of application is more and more wider, operating area becomes increasingly complex, and how can make unmanned plane work capacity of will more Gao Gengqiang, it is more convenient to use, and is the direction of unmanned air vehicle technique development.
Series compensation is the inductance of transmission line, may cause rising or the reduction of voltage:
(1) when flowing through capacity current in circuit, the inductance of transmission line can cause voltage to raise;
(2) when flowing through inductance current in circuit, the inductance of transmission line can cause voltage to reduce.
In long distance transmission line, series capacitor can be used to offset the impact of line inductance.Because series capacitor and line inductance are cascaded, electric current is identical, 90 degree, the voltage delay electric current of capacitor, the voltage leading current of inductance 90 degree, so capacitance voltage just just in time oppositely can cancel each other with inductive drop.When the capacitive reactance of series capacitor is equal with the induction reactance of line inductance, the voltage of line inductance is just offset completely with capacitance voltage, so the ability to transmit electricity of electrical network improves greatly, voltage stability also improves greatly.

In series compensation station, when series compensation device normal operation, many groups capacitance group, the circuit everywhere of distribution on it all can send electromagnetic wave due to maxwell theory, interference unmanned plane normal flight.
For protection capacitance group safety, string is mended in station and is devised a lot of spark gap.Electric line is picked in a pole of spark gap, another pole ground connection, and when circuit is normal power-frequency voltage, gap can not be breakdown, and circuit separates with ground.When dangerous overvoltage appears in electric power system, spark gap is then breakdown, and electric current flows into the earth by valve-type resistance.After having served as loss of voltage, power frequency continued flow cuts off by spark gap, restores to the original state.And when spark gap is breakdown, spark gap just becomes powerful electromagnetic interference source.
Except spark gap, during folding circuit plug-in strip, string mends energising in device all can produce complicated electromagnetic wave everywhere because of the instantaneous variation of electric current, and then the normal operation of interference unmanned plane.
In addition, some parts in unmanned plane also may be subject to electromagnetic interference, such as: flight control modules itself, receiver module itself, line between receiver module and flight control modules, flight control modules and electricity adjust between line, wherein, flight control modules has become " antenna " with the pin of some electronic devices and components in receiver module in the environment of electromagnetic interference, can interference signal be received, thus unmanned plane normal flight can be disturbed; Line between receiver module and flight control modules, flight control modules and electricity adjust between line, what they transmitted is control signal, holding wire circuit is long, cruelly leaks in addition and is just very easily disturbed in electromagnetic interference environment, and it is also very large to be disturbed the rear impact on unmanned plane generation.
