PROTECTION OF VARIABLE FREQUENCY DRIVES

teempimg.png

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

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.

SUPERCAPACITORS FOR CARS WITH “MILD HYBRID”

Connection of the ultracapacitor to the car electric circuit
Mounting location of the supercapacitor module (under the passenger seat)
TATA Nano Car
Joint studies have been performed along with TATA Motors LTS (India) to use the mild-hybrid in cars to smooth the car battery loads as well as to accelerate the vehicle and regenerate its braking energy.
The use of a supercapacitor in connection with storage batteries made it possible to significantly reduce the power of the battery discharge during a peak load.
ТThe battery current was reduced from 6C to 1.5C.
According to TATA experts, the reduction in the storage battery discharge current results in a 2-3-fold increase in the battery life.
Besides, based on the energy consumption control system of the car the supercapacitor was “charged” from the car battery or using regenerative energy whenever the load capacity was low..
