ABSTRACT: A control device for point-on-wave closing or autoreclosing of
shunt reactor compensated transmission lines for the reduction of
closing overvoltages is presented. The device is the first of its kind.
It was put into field service successfully more than a year ago.
Development aspects and basic investigations on the relevant transient
switching phenomena are presented. The algorithm employed works
independently of the shape of the voltage signal to be synchronized on
by means of pattern recognition. Peculiarities of the hardware are high
redundancy and a system to bypass the controller at any malfunction of
the electronic circuits. The efficiency of the controller was verified
by a combination of transient network analyser tests and EMTP
simulations showing the ability of the device to suppress overvoltages.
This procedure is generally recommended for future application of
control devices as a type test procedure
