WOODWARD 8200-1300 Digital Steam Turbine Controller

The WOODWARD 8200-1300 belongs to the Peak 150 digital steam turbine controller series, alongside the 8200-1312 you previously inquired about. It is the model within this series designed for low-voltage DC power supply environments and is recognized in the industrial sector as a reliable speed control solution.

1. Product Overview

The Woodward 8200-1300 is a digital regulator specifically designed for single-valve or single-actuator steam turbines. It integrates speed monitoring, process control, and equipment protection functions into a single unit.

The primary difference between this model and the 1312 model lies in the input power supply:

8200-1300: Designed for 24V DC (18–40V DC) power supply systems.

8200-1312: Designed for 120V AC/DC high-voltage power supply systems.

2. Key Features and Technical Specifications

High-Precision Speed Control: Utilizes a 16-bit microprocessor to deliver exceptional speed control accuracy and dynamic response.

Dual Dynamic Parameter Settings: Enables configuration of two independent PID parameter sets for different turbine operating phases (e.g., cold start and loaded operation).

Critical Speed Avoidance: Supports up to three configurable critical speed avoidance bands to prevent prolonged turbine operation at resonance frequencies, safeguarding mechanical structures.

Flexible Input/Output:

Redundant Speed Input: Supports dual MPU (magnetoelectric sensor) inputs with automatic switching upon loss of primary signal.

Cascade Control: Accepts external 4-20mA signals (e.g., inlet pressure, exhaust pressure, compressor flow) as auxiliary control loops.

Robust Industrial Protection: Modular design with NEMA 4X-rated front panel for superior vibration resistance.

Application Scenarios

Due to its 24V DC power supply characteristic, the 8200-1300 is commonly used in industrial sites with DC backup battery banks:

Backup Pump Drive: For emergency feedwater pumps or lubricating oil pumps driving turbines in petrochemical plants.

Small-Scale Cogeneration: Used in small to medium-sized factories to regulate backpressure turbines, maintaining constant production steam pressure.

Compressor Stations: Drives centrifugal compressors, automatically adjusting speed according to process requirements.

Harsh Environment Retrofits: Serves as a modern electronic replacement for outdated mechanical speed controllers
