Upgraded power unit No. 3 commissioned at the Saratovskaya HPP  

 
149
 
Power unit No. 3 had been in operation since 1968. During its rehabilitation in the third and 
fourth quarters of this year, its equipment was fully upgraded. A more powerful unit transformer 
(TRDTs -320000/220) was installed; shielding current distributors were laid anew; the 220 kV 
oil-filled power cable was replaced with the cross-linked polyethylene cable; generator 
switchgear (HECS-80M generator circuit-breaker systems and disconnect switches), relay 
protection and automatic equipment, regulator systems and auxiliary equipment were assembled. 
The power unit comprises two pairs of synchronous hydrogenerators, of which generator No. 10 
was upgraded in 1999 and generators Nos. 11 and 12 in 2005, and modernization of 
hydrogenerator No. 9 is scheduled to be completed in March 2010.  
 
Overall, there are five such power units at the Saratovskaya HPP. Observations have been held to 
determine the degree of their actual wear. Also, the project and schedule for their upgrading, 
involving replacement of all equipment, have been developed.  
 
Within the framework of this project, power unit No. 3 was the first to be upgraded. Advanced 
high-tech equipment for the unit was designed and produced by the European electrical 
engineering group ABB Power Technologies, taking into account the specifics of the 
Saratovskaya HPP. The main contractor for construction and assembly work was JSC 
Elektroremont-VKK; a considerable amount of work was fulfilled by the subcontractor CJSC 
INESS (town of Balakovo). All operations are ongoing under the guidance of the power plant's 
technical personnel. Equipment manufacturers and suppliers and work contractors have been 
selected through tenders.  
 
New equipment has a longer service life, is environmentally safe, compact and easily 
serviceable, helps reduce transmission power losses and has an overhaul cycle limit of 30 years. 
Monitoring systems make it possible to track more closely the power unit's operational 
parameters to enhance its functional reliability and the quality of equipment performance 
monitoring.  
 
In June 2010, after the spring floods are over, upgrading of another power unit will start at the 
Saratovskaya HPP. There are plans to modernize one power unit a year and wrap up works in 
2013. Therefore, this is one of the largest projects under the equipment upgrading program for 
the Saratovskaya HPP, with the cost of works under the project estimated at more than 1.4 
billion rubles. Implementation of the project will help maintain the necessary power reserve in 
the Balakovo power hub and the Middle Volga area and enhance HPP operation reliability.  
 
The ongoing works clearly demonstrate the scope of the long-term equipment rehabilitation and 
upgrading program. Initial work under the program began in 1995 and all the basic and auxiliary 
equipment of the Saratovskaya HPP is to be upgraded by 2030.

Upgraded hydroelectric unit put into operation at the Kamskaya HPP 
 
 
Rehabilitation of hydroelectric unit No. 23 has been completed at the Kamskaya HPP to increase 
its installed capacity by 3 MW. The unit rehabilitation program started in 1997, and hydroturbine 
No. 23 became the 15th turbine that had been rehabilitated. Overall, the HPP has 23 vertical-axis 
Kaplan turbines with the rotor wheel diameter of 5 meters.  
 
The rotor wheel, the guiding device and other parts of unit No. 23 were manufactured by JSC 
Tyazhmash. Originally, the turbines for the Kamskaya HPP were produced by the Syzran 
hydroturbine manufacturing plant, which was eventually integrated into JSC Tyazhmash. Now, 
after about 50 years, the producer has resumed equipment deliveries to the Kamskaya HPP.

In the course of rehabilitation, the unit's turbine and generator were improved. A new rotor wheel 
was installed on the upgraded turbine, considerably reducing the risk of turbine oil leak from the 
regulator system into the Kama River. This made the hydroelectric unit more environment 
friendly and considerably improved its reliability and performance.  
 
During assembly work, HPP personnel closely monitor the quality of main parts of hydroelectric 
units. If breaches of the requirements for repaired equipment are detected, the faulty parts are 
mandatorily replaced, as was the case with the upper flange plate of the turbine cover in unit 
No. 23.  
 
“Hydroelectric unit No. 23 manufactured by JSC Tyazhmash for the Kamskaya HPP has become 
a sort of a flagship”, says Vladimir Buss, deputy director of JSC RusHydro's branch Kamskaya 
HPP. “Currently, JSC Tyazhmash is fulfilling the orders for the manufacture of equipment for 
hydroelectric unit No. 17 and preparations have been launched for the manufacture of another 
three units. Mindful of the need to keep domestic companies operating, the managers and 
specialists of the Kamskaya HPP maintain a constructive dialogue with equipment manufacturers 
and hope that the experience accumulated in the process of rehabilitation of hydroelectric unit 
No. 23 will contribute to the parties' mutual understanding”.  
 
Currently, integrated live tests are being held to check output performance of equipment, 
following which documents will be prepared for equipment remarking. The upgraded 
hydroelectric unit will have a capacity of 24 Mw while the HPP's installed capacity will amount 
to 522 MW.

2009 tasks for construction of the Bureiskaya HPP fulfilled 
  
A regular meeting of the startup operations staff for construction of the Bureiskaya HPP was 
held under the chairmanship of JSC RusHydro Management Board Member and Far Eastern 
Division CEO Yuri Gorbenko.  
 
The staff members discussed the results of fulfilling the 2009 assignments for construction of the 
Bureiskaya HPP, one of the largest investment projects of RusHydro, and mapped out plans for 
the near future.  
 
In 2009, more than 6.6 billion rubles were spent on implementing the HPP construction project, 
including 2.7 billion rubles channeled into the financing of construction and assembly work. As 
a result, the third hydroelectric unit was put into operation in accordance with the standard 
procedure and the hydropower plant reached its design capacity. In the summer of 2009, the 
reservoir reached its designed level for the first time, which made it possible to hold large-scale 
tests of the service spillway. Hoisting cranes were put into operation on the crest of the dam to 
ensure gate operation. The transformer repair shop in the hollow of the dam and a public 
amenities center were built.  
 
In 2010, construction of HPP site facilities and the tailrace channel will be completed, as well as 
construction of the utility and production block and the building for the instrumentation and 
control system. The oil transformer building will be properly fitted out. Implementation of the 
program will require about 1.2 billion rubles.  
 
The operations staff members discussed the issues of enhancing reliability and safety through 
making changes to the design and construction sections, taking into account new trends in hydro-
engineering construction, HPP operation practices and new requirements of the Federal Service 
for Environmental, Technological and Nuclear Supervision (Rostekhnadzor).

“The year 2011 will see completion of the Bureiskaya HPP construction project”, Yuri Gorbenko 
said in conclusion. “We must prepare the facility for acceptance by the government 
commission”.

Volzhskaya HPP puts an upgraded hydroelectric unit into operation  
 
Hydroelectric unit No. 3, with its capacity increased from 115 to 125.5 MW, was launched into 
operation after rehabilitation at JSC RusHydro's branch Volzhskaya HPP.  
 
This is the third fundamentally new turbine. It differs from the turbines originally installed at the 
hydropower plant in terms of both design features and assembly. It has a service life of 40 years.  
 
“A structurally new type of the rotor wheel has been installed on hydroelectric unit No. 3, as well 
as a modern control system complying with international standards. Modern seals of rotor wheel 
blades exclude the leak of turbine oil into the Volga River, giving the grounds to consider the 
new turbine to be environment friendly”, Sergei Talagayev, chief engineer of the Volzhskaya 
HPP said.  
 
Rehabilitation of the third hydroelectric unit started in mid-2008. The cost of equipment and 
construction and assembly work totaled 1.4 billion rubles. Turbine replacement payments are 
made by installments under a lease scheme. The following organizations were involved in unit 
rehabilitation efforts: JSC Power Machines (St. Petersburg), CJSC Spetsenergomontazh (town of 
Volzhsky), JSC Gidroremont (town of Volzhsky).  
 
Today, eight out of the HPP's 22 hydroturbines with the expired lifespan have been replaced. The 
remaining turbines are to be rehabilitated by 2020 under the long-term HPP equipment 
upgrading program.  
 
Overall, JSC RusHydro's branch Volzhskaya HPP spent over 600 million rubles on equipment 
upgrading and rehabilitation in 2009. The list of basic works included complete rehabilitation of 
two turbines, rotor wheels modernization for two hydroelectric units, replacement of three 
generator air circuit breakers with SF
6
 circuit breakers, complete replacement of thyristor 
excitation systems at 22 hydrogenerators, complete rehabilitation of 26 edges of the overfall 
dam, initial rehabilitation of the central oil lubrication system, rehabilitation of unit transformers 
with the installation of an explosion/fire protection system (mounted on six transformers), 
replacement of the spillway's emergency and repair gates and trash racks.
