Voltage setpoint of ARV-M is changed on 5%in 5 sec. Combined operation of ARV-M and

ARV-CD in the scheme of doubled unit of Ust-Ilim HPP

50

Tuning on the «turn key» bases is producedfor significant objects of the power system

(HPPs and NPPs of large rated power)

• Sayano-Shushenskaya HPP (6.4 GW)• Ust-Ilimskaya HPP (3.5 GW)• Zagorskaya HAPP (1.2 GW)• Kolskaya NPP (1.44 GW)

• Kalininskay NPP (3 GW) – January 2010• Boguchanskaya HPP (3 GW) – February 2010• Smolenskaya NPP (3 GW) – March 2010

51

Conclusions

Tests held according to the «Program…» provide AVRand PSS efficiency assessment and their adaptationto the conditions of operation in UPS of Russia.

Correctness and efficiency of AVR and PSS tuning ischecked using digital and physical models of the powersystems.
