Implementation of uninterruptible power supply unit (UPSU), 20kVA capacity, with network bypass at Belozerny GTP OJSC (Sibur-Holding OJSC)

BPA has implemented a complex project for implementation of an uninterruptible AC power supply unit of PDW-R series (GUTOR) intended for power supply of three-phase and single phase electrical energy essential service requiring high quality feed voltage and placing special requirements to power supply stability.

UPSU provides power supply to APCS, control instrumentation and actuating mechanisms of two main process plants of the Belozeny GTP.

High quality of output voltage of the System is provided by employment of double conversion technology. High reliability is achieved due to redundancy (backup) of uninterrupted power supply modules (UPS), and due to employment of an auxiliary (bypass) in-feed.

The system is composed of two identical AC UPS modules and a bypass cabinet. The functional structure of the System includes also two accumulator batteries (one for each UPS module), which are supplied separately.

UPSs of PDW series are designed for power supply of three-phase and single phase electrical energy consumers requiring high quality feed voltage. Each UPS module is a full-range AC power supply unit with double electrical energy conversion (~/=/~).

UPS module consists of a controlled thyristor rectifier converting three-phase input ac voltage in the mains into dc voltage of a buffer circuit, and an inverter transistor converting dc voltage of buffer circuit into output three-phase ac voltage.

If input circuit voltage is available, the rectifier feeds the inverter and simultaneously provides charge to the accumulator battery in optimum regime (for extended life of the battery).

The inverter converts dc voltage of the buffer circuit into output ac voltage. The conversion is provided by commutation of power transistors with employment of pulse-length digitally controlled (regulated) modulation. If circuit voltage is available, the power source for inverter is the rectifier, if no voltage in the circuit – the accumulator battery.

In addition to the above main components of the inverter and rectifier, UPS module includes protective switching units, fast power static switches, as well as a microprocessor-based controller that controls all UPS module equipment.

Bypass cabinet provides a possibility of power supply to the electric energy consumers from auxiliary (bypass) power supply and is composed of the following equipment: three-phase insulating transformer, manual 3-way switch of bypass, protective switching devices.

Monitoring systems of power transformer equipment

Monitoring Systems (MS) of parameters of power transformer equipment, voltage rating 110-1250kV, are designed for continuous measuring and recording of critical parameters of transformers, autotype transformers and reactor coils while in operation. The present-day MS systems make it possible to detect any malfunction in the operation of power transformers and other equipment of substations in early stages of their occurrence, and, therefore, to take a decision on their elimination before any contingency. It does not only prevent any significant damage, but it cuts shutdown time, reduces expenditures for repairs and extends the service life of transformers.
