Keywords: transmission line, series reactor, shunt reactor, shunt capacitor, shunt compensation, series compensation. I. INTRODUCTION In the early days, generation, transmission and distribution of electricity were in most cases DC current. DC systems posed problem which is the fact that the level of the voltage was difficult to change.
I. Product use. Dry type hollow series reactor is suitable for 6, 10, 35kV power system, connected in series with shunt capacitors, used to suppress the voltage waveform distortion of the power grid, so as to change the quality of the power grid and ensure the safe operation of the power system; The harmonic current flowing through the capacitor bank is suppressed and the inrush
It could be said that series capacitors produce more net increase of voltage which produces more voltage drops in the system. Conclusions An emulator is used to test an inductive shunt reactor in the cases of high voltage transmission lines in order to stabilize the voltage during changes of the load.
One of the unwanted effects is the overheating of capacitor banks that are needed to maintain the power factor within the parameters required by the power authority, with a resulting, significant reduction in the average working life. The ideal solution is to insert block reactors in series with capacitor banks.
Power flow control reactors, which are series-connected to transmission lines, regulate the current into two or more parallel circuits. Series reactors can also be used for many other applications such as capacitor banks inrush/outrush, motor-starting and arc-furnace current limiting, or as part of series compensation discharge circuits.
The frequency of these uniterrupted oscillations is reduced by the use of shunt reactors across the capacitors or even short circuiting the capacitors temporarily. It could be said that series capacitors produce more net increase of voltage which produces more voltage drops in the system.
In most cases, this voltage drop is small compared to the normal system voltage fluctuations and no additional action is required. The voltage drop across the reactor for a combined zone substation loading of 17 MW at a power factor of 0.7 is approximately 1%, as shown in Figure 4. Figure 5: Voltage drop after the addition of the series reactor.
The series reactor shall be outdoor type, 50Hz, air cooled, air core type of Cu material. Series reactors shall be capable of withstanding the specified short circuit currents. The percentage series reactance shall preferably be 0.2%. The series reactors shall conform to type tests and shall be subjected to routine tests as per IS.
