DEIF TCM-2 thyristor control module

Basic Information

Model: TCM-2 Thyristor Control Module, DEIF New Energy Wind Power Special Controller

Core application scenarios: onshore/offshore wind turbines, asynchronous motor soft start equipment, focusing on grid connected control of wind turbines

Advantages of Product Core Environment Reliability

TCM-2 follows the strict design standards of DE marine/offshore equipment and is suitable for harsh working conditions:

Working temperature range: -25 ℃~+70 ℃, far exceeding the temperature range of conventional industrial controllers;

High anti vibration structure design, perfectly adapted to the turbulent vibration environment of offshore wind power and onshore wind turbine cabins;

3. The whole machine has strong durability and is specially designed for long-term unmanned wind turbine working conditions.

Two operating modes

TCM-2 supports two architectures: independent single machine autonomous operation and CAN bus slave control, adapting to different wind power control system solutions:

Stand alone mode

By only connecting a small number of standard industrial analog/switch signals, the complete set of thyristor real-time voltage regulation and grid connection control logic can be autonomously executed without the need for real-time intervention from the upper level main controller, making it suitable for simple wind turbine electrical control solutions.

CAN bus slave mode

Connect the upper level main process controller through the CAN bus, and receive real-time adjustment instructions from the upper level. TCM-2 only performs thyristor power adjustment and is compatible with the entire wind power integrated control system.

Core innovation: Adaptive cut in algorithm for wind turbines

This is the most core technological highlight of TCM-2, used for grid connection and closing control of asynchronous wind turbines, significantly reducing the impact load of the transmission chain:

1. Defects of ordinary traditional entry solutions

The traditional approach would complete the excitation of the generator before the speed is synchronized, causing the generator to briefly operate in the state of an electric motor and generate a huge impact power:

Minimum impact power Pmin: 30.4kW

Peak impact power Pmax:+610.6kW

Duration of impact Δ t: 0.56s

Total impact energy Δ E: 443.5kJ

The huge instantaneous load severely damages transmission components such as gearboxes and main shafts, shortening the lifespan of the fan.

2. TCM-2 adaptive cut in optimization principle

Accurate matching of speed timing, excitation is only completed at the moment when the generator reaches synchronous speed, completely avoiding reverse impact of motor operating conditions:

Minimum impact power Pmin: only 11.4kW

Peak impulse power Pmax:+393.6kW

Duration of impact Δ t: 0.78s (slight elongation, smoother load)

The total impact energy Δ E has decreased to 136.6 kJ, which is about 69% lower than the traditional solution

Significantly reduce the mechanical stress on the main shaft, gearbox, and blades, lower maintenance and replacement costs, and extend the service life of the entire fan.

Standard application scope

Wind turbine grid connection controller (core application): soft grid connection control for cage type asynchronous wind turbines;
