HYDROPOWER PLANTS

Our company has extensive experience in both the modernization of existing hydroelectric power plants and the calculation of new hydroelectric power plants.
In this area, we act not only as power engineers and automation engineers, but also as technologists who will help you choose the optimal solution for the project. We design, manufacture, install, and carry out commissioning of systems for hydroelectric power plants.

SCADA SYSTEM

The SCADA system will implement:
- information collection;
- conversion and analysis of received information;
- information processing in run-time mode;
- data archiving;
- information visualization in the form of mnemonics;
- creation of graphs;
- information presentation in the form of tables;
- accident protocol;
- event protocol;
- possibility of sending information messages via the Internet;
- possibility of integration into the upper (central SCADA) (when several generation facilities are reduced to one central dispatching point with synchronization of all data);
- local and remote (via the Internet via a secure channel) control of the station with editing of the operating parameters of the HPP;
- operation in the water level=const mode;
- operation in the cosⱷ=const mode;
- operation in the Pact.=const mode;
- operation in the Qact.=const mode;
- operation in generator priority mode (even engine hours, machine removal for repair);
- possibility of setting time settings for equipment operation.

TURBINE GOVERNING DEVICE (SPEED) REGULATORS

- hydraulic;
-electromechanical.

SELECTING A HYDROGENERATOR

SYNCHRONOUS:
- with static excitation;
- on permanent magnets;
- low or medium voltage;

ASYNCHRONOUS:
- low voltage (0.4 kV);
- medium voltage (10.5 kV).

REACTIVE ENERGY COMPENSATION SYSTEMS OF INDUCTION GENERATORS (AG)

- for low-voltage machines;
- for medium-voltage machines.

AUTOMATION AND CONTROL SYSTEM

PLC (programmable logic controller) will allow to provide:

Control network analyzers provides protection:
- by voltage frequency;
- protection against asynchronous operation;
- minimum active and reactive power;
- maximum active and reactive power;

Control synchronizers (smooth synchronization):
- by voltage;
- by frequency;
- by phase shift;

Voltage relay provides protection for:
- phase distortion;
- overvoltage;
- undervoltage;
- phase alternation (protection against switching on in antiphase);

Zero sequence transformer:
- protection against ground faults;

Speed ​​sensor:
- protection by generator revolutions;
- understanding of the generator state (with closed sandors - should not rotate);

Level gauge (hydrostatic type, allows correct operation in all seasons):
- control of water level in the upper reaches;
- when delivering another level gauge, control of the lower reaches;
- when delivering two more, control of the state of contamination of the cleaning grids;

Using a light column (three colors: green, yellow, red) and a sound siren, inform personnel about changes in the operation of generators (stop, start, stop, accident, breakdown);

Also, by building dependencies between the parameters of various equipment, additional algorithms of operation and protection can be built (for example, self-retraction mode into the network, slip control, etc.).

SELECTION OF HYDROTURBINES

- Pelton turbine;
- Francis turbine;
- Kaplan turbine;
- Archimedes turbine;
- Siphon type turbine.

HEATING SYSTEMS AND CLEANING OF WATER RECEIVER GRIDS

- the grates are designed in such a way as to avoid clogging them with snow;
- automatic cleaning of the grates using a mechanized manipulator.

SYNCHRONOUS GENERATOR (SG) EXCITATION SYSTEMS

- reconstruction of PVA and RNA installations, as well as their analogues for machine exciters;
- reconstruction of shunt excitation;
- implementation of static thyristor excitation from the power supply of the own needs switchboard;
- implementation of static thyristor excitation from the power supply from generator buses;
- implementation of static thyristor excitation with parallel operation from an independent source for autonomous generator operation.
