Typical application areas

High voltage frequency converter system

In high-voltage frequency converters (such as the ACS 2000 series) in industries such as steel, mining, and power, as the core drive control module of each power unit, it receives PWM instructions from the main controller of the frequency converter, drives the IGBT module to achieve AC-DC-AC power conversion, and monitors parameters such as DC bus voltage and IGBT temperature of the power unit. When overcurrent, overheating and other faults occur, immediately cut off the drive signal and provide feedback on the fault information to ensure the safe shutdown of the frequency converter and avoid major equipment accidents caused by damage to power devices.

Static Var Generator (SVG)

In the reactive power compensation devices of power systems and metallurgical enterprises, IGBT modules used to drive SVG power units inject or absorb reactive power into the grid by accurately controlling the switching state of IGBT, improving the power factor of the grid and suppressing voltage fluctuations. The module monitors the operating parameters of the power unit in real-time to ensure that SVG can stably output reactive power compensation current even when the power grid load changes dramatically (such as electric arc furnace steelmaking), ensuring the quality of power grid.

High voltage motor soft starter

In the soft start system of high-voltage motors in the petrochemical and cement industries, the IGBT power unit inside the soft starter is controlled to achieve smooth regulation of voltage and current during the motor starting process, avoiding the impact of excessive starting current on the power grid and motor. At the same time, monitor the current and temperature parameters during the motor start-up process. If there is an abnormal start-up (such as stalling), immediately trigger the protection mechanism, cut off the motor power supply, and protect the motor and soft starter equipment.

Energy Storage Converter (PCS)

In the new energy storage system, as the driving control core of the energy storage converter, the IGBT module is coordinated to achieve bidirectional conversion (charging/discharging) between battery energy storage and the grid. The module precisely controls the charging and discharging current and voltage to ensure stable operation of the energy storage system according to scheduling instructions, while monitoring the status of the inverter power unit to prevent battery damage and inverter faults caused by overcharging, overdischarging, or overheating.

Key points of installation and operation and maintenance

（1） Installation specifications

It needs to be installed on the dedicated heat dissipation substrate of the high-voltage equipment power unit, with a flat installation surface (flatness ≤ 0.1mm) and coated with thermal conductive silicone grease (thermal conductivity ≥ 3W/m · K) to ensure a tight fit between the module and the heat dissipation substrate and improve heat dissipation efficiency; A space of ≥ 20mm should be reserved around the module to avoid collision with other components and ensure air circulation.

Before wiring, the main power supply and control power supply of the high-voltage equipment must be disconnected, and insulated tools must be used for operation. The high-voltage power terminals (such as IGBT drive terminals) and low-voltage control terminals (such as PWM signal terminals) must be strictly distinguished, and mixing is strictly prohibited; The control signal line needs to use shielded twisted pair (such as AWG24 shielded wire), with the shielding layer grounded at one end (grounding resistance ≤ 1 Ω) to avoid electromagnetic interference affecting the accuracy of the driving signal.

The power terminal wiring needs to be tightened with a torque wrench according to the specified torque (reference value: M4 screw tightening torque 1.2-1.5N · m) to prevent overheating of the terminal due to poor contact; Cold pressed terminals should be used for control terminal wiring to avoid exposed copper wires and prevent short circuit faults.

（2） Debugging and Calibration

Before the initial debugging, use an insulation resistance meter to measure the insulation resistance of the module's high and low voltage circuits (≥ 100M Ω/500V DC), and confirm that the insulation performance is qualified; Connect the control power supply and auxiliary power supply, check if the module power indicator light (PWR) is lit up normally, and if there is no fault alarm indicator light (FAULT) lit up.

Drive signal calibration: Input a standard PWM signal (frequency 5-15kHz, duty cycle 0-100%) to the module through a signal generator. Use an oscilloscope to measure the drive signal output from the module to the IGBT, confirm that the amplitude (± 15V), frequency, and duty cycle of the drive signal meet the design requirements. If there is a deviation, adjust the drive signal strength through the calibration potentiometer on the module (such as DRV-ADJ).

Monitoring parameter calibration: For the module voltage monitoring channel, input standard DC voltage (such as 500V, 1000V, 2000V), read the module monitoring value through the upper computer software, and if the deviation exceeds ± 0.5%, perform linear calibration in the software; For the temperature monitoring channel, use a temperature simulator to simulate different temperature values (such as 50 ℃, 100 ℃, 150 ℃) and calibrate the temperature monitoring accuracy.

Fault protection test: Simulate overvoltage (input exceeding rated voltage by 120%), overcurrent (input exceeding rated current by 150%), and overtemperature (simulating IGBT junction temperature of 180 ℃) scenarios, check whether the module can trigger protection within 1 μ s, cut off the drive signal and output the fault contact signal, and whether the upper unit can accurately receive fault information.

（3） Maintenance strategy

Daily maintenance (monthly): Check the module operating parameters (such as drive signal amplitude, monitoring voltage/temperature values) through the upper computer monitoring software to confirm that there are no abnormal fluctuations; Check the appearance of the module for bulges and burn marks, and the heat dissipation substrate for dust accumulation. If there is dust, it needs to be cleaned with compressed air (pressure ≤ 0.2MPa).

Regular maintenance (quarterly): After power failure, disassemble the module and check if the thermal grease between the module and the heat dissipation substrate has dried up. If it has dried up, reapply the thermal grease; Check whether the wiring terminals are oxidized or loose, and tighten the loose screws again; Use a multimeter to measure the module control power supply voltage (± 15VDC, 24VDC) and confirm that the voltage is stable within the rated range.

Annual maintenance: Conduct comprehensive performance testing on the module, including driving signal response time testing (measured using an oscilloscope, required to be ≤ 100ns), fault protection response time testing (simulated overcurrent using a high-speed current source, required to be ≤ 1 μ s); If the module has been running for more than 3 years, it is recommended to replace the electrolytic capacitors inside the module (if any) to prevent capacitor aging and module failure.

Fault handling: If the module has a fault alarm (FAULT light on), first check the fault code (such as "F01: overvoltage" and "F03: undervoltage of the drive power supply") through the upper computer, and identify the corresponding fault point (such as DC bus voltage and control power supply) according to the code; If the fault cannot be eliminated, the spare module needs to be replaced. When replacing, it is necessary to ensure that the new module model is consistent with the original module to avoid equipment damage caused by parameter mismatch. The old module needs to be repaired by contacting an ABB authorized service provider.
