Description

The ABB PPD512A10-150000 exciter is a static excitation system controller produced by ABB, widely used in the excitation control of synchronous generators. The following is a detailed analysis of the product:

1、 Product Overview
Model and specification: PPD512A10-150000, is an important component of ABB’s static excitation system. The model parameters may include specific codes such as 3BHE040375R1023, which are used to identify the detailed specifications and configurations of the product.

Function and Application: This exciter controls the excitation current through a thyristor rectifier bridge, achieving the purpose of regulating the synchronous generator terminal voltage and reactive power. It is suitable for various DCS/PLC industrial control systems, such as AC 800PEC, providing stable and reliable excitation control for generators.

2、 System composition and working principle
System composition: ABB PPD512A10-150000 excitation system usually includes key components such as excitation regulator, thyristor rectifier unit, excitation unit, and demagnetization unit. These components work together to ensure the stable operation of the excitation system.

working principle:

Excitation transformer: reduces the generator terminal voltage to the input voltage required by the thyristor rectifier bridge, while providing electrical isolation between the generator terminal voltage and the magnetic field winding, and providing rectification impedance for the thyristor rectifier.

Controllable silicon rectifier bridge: converts AC current into controlled DC current and supplies it to the generator field winding.
Excitation process: At the beginning of excitation, the excitation energy of the engine comes from the residual voltage of the generator. When the input voltage of the thyristor rectifier rises to a certain range (such as 10V~20V), the thyristor rectifier bridge and excitation regulator are put into normal operation, and the soft excitation process is controlled by the AVR (Automatic Voltage Regulator).
3、 Product Features
Fully automatic operation: The PPD series excitation controller can achieve fully automatic and unmanned operation of excitation control with just one click of start.
High precision control: Through advanced control algorithms and precise execution mechanisms, ensure stable control of generator terminal voltage and reactive power.
High reliability: Using high-quality components and strict production processes to ensure the high reliability and long life of the exciter.
