The coordinated generation and load control to increase transient stability level of oil- production enterprise autonomous power system with dominant motor load is studied in the paper. Mutual angle between voltage phasors at gas turbine plant bus and equivalent load node as well as slip difference of synchronous machines are used as input signals. It is shown that implementation of additional control allows to increase the level of transient stability by more than 40%. The combined coordination of power system stabilizer of synchronous generators and motors as well as gas turbine frequency control parameters is applied. The positive impact of power system stabilizer settings on post-accident conditions is proved by analysis of small signal stability.
