Main

A proper assessment of transients at the design stage is particularly important. The design solutions should ensure the operability of the water supply system and equipment in all situations arising during operation. Practice shows that the only reliable means for solving this problem is the use of mathematical models describing the operation of the projected station in transient processes.

Programs

The programs for the calculation of the transient processes of the diversion HPPs (and separately for the PSPP) with branched pressure pipe systems, presure relief valves, upstream and downstream surge tanks allow investigating transients in the pressure system, hydraulic machine, automatic control system of the units and station level, and the isolated power system.

The programs can be transformed into computer models of specific HPPs and PSPPs for use in the automatic control subsystems.

Mathematical modeling of transient processes of HPPs, PSPPs and PSs

The practice of participation in projects, competition in the market of design services indicate an increase in the requirements for the validity, reliability and cost-effectiveness of design solutions, which puts forward studies of the transient processes of HPPs, PSPPs and large pumping stations.

Transient processes have a decisive influence on the composition and design parameters of the pressure systems of derivational HPPs and PSPPs, as well as determine the nature of the change in the plant’s power, which is necessary to assess the regulatory capabilities of HPPs in the power system.

The correct estimation of transients at the design stage is especially important. The design solutions should ensure the operability of the water supply system and equipment in all situations arising during operation. Practice shows that the only reliable means for solving this problem is the use of mathematical models describing the operation of the projected station in transient processes.

Field testing of hydraulic units of hydroelectric power stations and pump stations

Field testing of the HPP and pump station units in steady-state conditions and during transient processes remains one of the main activities of the White Coal, ltd. Tests are carried out to calibrate flowmeters in absolute ways, determining the efficiency, power consumption and performance characteristics of the units, the power characteristics of the directing device, to optimize the settings of the turbine regulators and group control systems.
