OREANDA-NEWS. January 11, 2011. The system of governor of active and reactive power (GRARP) was developed for the Ust-Kamenogorsk hydropower plant (HPP) by OOO "SPC"Rakurs". The system GRARP was tested successfully on the digital-analog-to-physical complex of JSC "Scientific-Research Institute for the transmission of high voltage direct current” (SRITC).

From 8th to 17th November, 2010 were passed the tests of GRARP system into the program, which developed by JSC”SRITC” under the contract with OOO "SPC"Rakurs" and agreed with the customer of LLP “AES Ust-Kamenogorsk HPP” and the system operator of “Kazakhstan Company for Electricity Grid" affiliate of a ‘National Dispatching Center”.

The tests on the models allowed checking the work of control group in terms as close as it possible to the conditions of the station. The parties were satisfied with the results of the tests. The developers were having the necessary experience setting up control loops. During the tests were chosen optimal values of dynamic parameters of the main regulators, as well as provided useful recommendations for the refinement of control algorithms in emergency mode of emergency conditions.
