PROTECTION OF VARIABLE FREQUENCY DRIVES
Challenge
Disconnection of the variable frequency drive, including the actuators of the shut-off and control equipment, during voltage drops and a short-term, up to 10 seconds, loss of voltage in the network.
Solution
Power supply system of the variable frequency drive with an energy storage unit based on supercapacitors.
Connection is both feasible with a single variable frequency drive and a series of drives.
The system capacity and operating time are determined at the development stage of the terms of reference as required by the Customer.
Application:
- Equipment for sites of continuous process cycle;
- Equipment for supplying an enterprise with gas, water, heat, electricity (the shutoff and control fittings, compressors, pumps, boilers, etc.);
- Equipment that is sensitive to variable voltage and a short-term voltage loss.
TEEMP collaborates with the developers and manufacturers of power converters: NPK Morsvyazavtomatika, SNE LLC, Danfoss, Freqcon
SYSTEMS FOR VOLTAGE DISTORTION COMPENSATION
System VDCS for variable frequency drives at oil refineries
The Voltage Distortion Compensation System (VDCS) is intended to protect the equipment against deep drops and interruptions in voltage, providing uninterrupted power supply to the infrastructure
Connection of the VDCS: in parallel to the existing automatic circuit breaker of the enterprise distribution substation.

SOLUTIONS FOR VOLTAGE DROP COMPENSATION
Voltage Drop Compensation Device (VDCD) by TEEMP is a parallel switching device with its own power supply.
Parallel switching makes it possible to operate in a reactive power supply mode and also simplifies the device installation.
The selected power supply is a storage subsystem based on ultracapacitors:
- High discharge current, which is required to eliminate problems caused by power drops and interruptions;
- Supercapacitors are much more reliable compared to lithium and lead-acid batteries, and are able to operate under frequent charge/discharge conditions;
- The supercapacitors characteristics are less degraded over time;
- Supercapacitors require lower operating costs.
VDCD basic specs
- Rated voltage: 6 kV
- Rated power: 1,200 kV*A
- VDCD rated energy capacity: 1.97 kW*h
- VDCD energy capacity at the end of the system lifetime: 1.33 kW*h
- Model of the supercapacitor modules: МО-162V-50F
- Quantity of the ultracapacitor modules: 24
- Climatic modification: NF1
- Lifetime: 10 years
SOLUTIONS FOR HYBRID TRANSPORT
Belkommunmash city bus featuring TEEMP hybrid system
CONFIRMED FUEL EFFICIENCY OF THE HYBRID BUS – 27.7%
MORE EFFICIENT COMPARED TO A STANDARD BUS EQUIPPED WITH INTERNAL COMBUSTION ENGINE
The hybrid system consists of at least 2 power supplies. The first and main power supply is ICE, while the auxiliary power plant is a supercapacitor energy storage unit (ESU). The TEEMP storage unit is charged by the ICE and also by braking energy.
The main purpose of the supercapacitor ESU is to reduce fuel consumption by regenerating braking energy for further using it in acceleration mode.
