Nikolai Nikolaevich Kovalev graduated in 1925 from the Polytechnic School of Poltava in Central Ukraine and from the Leningrad Engineering Institute in 1930. For the next 28 years Kovalev was a design engineer of the Leningrad Metal Works, from 1945 as the chief designer of hydro turbines. In parallel he was from 1953 to 1967 a professor of hydro machinery at the Leningrad Polytechnic Institute LPI. From 1959 Kovalev directed the hydro turbine department of the Leningrad Central Boiler and Turbine Institute and was there involved in the design and the execution of the large turbines required for hydropower generation.

\

Kovalev is known for his outstanding designs of turbines for hydropower plants. He designed for example the aggregates of the Volga cascade scheme which involved revolutionary elements and he initiated a novel generation of turbines after World War II. Kovalev was also involved in the design of the radial inflow turbines for the Dniepr 75 MW power plants. His knowledge originated from stays at the LPI hydro-machinery department from 1939, where he returned as a professor in the 1950s. Kovalev was a Member of the Technical Council of the Machine Ministry, and a Deputy of the RSFSR Supreme Soviet. He was a Hero of the Socialist Labor from 1957, a Lenin Premium Laureate in 1959 and he was awarded Lenin Medals in 1946 and in 1950. Kovalev was a Corresponding Member of the USSR Academy of Sciences from 1953.
