  • Substation 750 kV Zakhidnoukrainska commissioned new reactors

    Substation (SS) 750 kV Zakhidnoukrainska commissioned and connected to the export overhead line 750 kV Zakhidnoukrainska – Albertirsha three lines of reactors R-14. The equipment is replaced in the framework of Ukrenergo Investment Program for 2018. The works for the replacement of reactors were completed within two months.

    “New equipment will significantly increase the reliability and efficiency of substation’s operation, will allow us to move to the establishment of automated systems of control over technological processes and decrease expenses for servicing power equipment in the nearest future,” said Oleksandr Vovchok, head of SS 750 kV Zakhidnoukrainska.

    New reactors will ensure stable quality indicators of electricity both for the consumers of “Burshtyn Island” and for European consumers when electricity is exported. In addition, the construction of devices provides for significant reduction in electricity consumption for substation’s own needs.

    The Investment Program also provides for the replacement of three lines of autotransformers AT-1 within the following two months at SS 750 kV Zakhidnoukrainska. As of today, one line of reactor P-5 is under replacement and one line of reactor P-1 and reactor P-6 are planned to be replaced at the substation. Ukrenergo continues works for the replacement of disconnecting devices, voltage transformers and bar supports at the connection to OHL 750 kV Zakhidnoukrainska – Khmelnytska NPP and complex modernization of relay protection.


    SS 750 kV Zakhidnoukrainska is the largest power station in Europe (70 hectares) with the installed capacity of 3000 MVA. The substation has direct electric connections under the voltage of 750 kV with Rivne NPP and Khmelnytska NPP; under the voltage of 330 kV with Burshtynska TPP and Lviv power centers. A separate part of the substation, which includes the connections of OHL 750 kV Zakhidnoukrainska – Albertirsha and OHL 330 kV Zakhidnoukrainska – Burshtynska TPP No. 1 and AT-3, operates in a parallel mode with the power system of Europe in the composition of “Burshtyn Island.”
