The Woodward 505D 8200 - 1302 is a digital governor control for steam turbines, featuring advanced functionality and wide - ranging applications. The following is a detailed introduction in English:
The 8200 - 1302 is a front - panel - mount, user - configurable steam turbine digital governor control. It is the next - generation product based on the reliable 505 platform, suitable for marine and ATEX zone 2 hazardous locations, with a low - voltage 18 - 36 VDC power input.
- Integrated Graphical HMI Screen
- It has an integrated graphical front - panel HMI screen. The screen is large, which allows for easy navigation and icon - view of parameters and performance. It also supports multilingual displays, including Chinese, to facilitate operation, diagnosis, and control by operators.
- Real - time trending can be viewed locally by operators and engineers, and tag names can be configured to easily identify connections. There is also an internal “turbine simulator” for off - line training and advanced testing before system changes.
- Control Functions
- Start - up and Speed Control: It provides auto - start sequencing for both hot and cold starts, with temperature input options. The acceleration PID limits overshoots, ensuring a stable and efficient plant startup. It can also avoid critical speeds in three - speed bands and has a speed accuracy of up to ± 0.05 %.
- Load and Speed Dynamics: Offers dual - speed and load dynamics, as well as peak - speed indication for overspeed trip, zero - speed detection, remote droop, and frequency dead - band functions.
- Alarm and Trip Management: It has ten external alarm inputs and ten external DI trip inputs. Trip and alarm events are indicated with associated RTC (Real - Time Clock) timestamps.
- Adaptive Control Algorithms: Equipped with intelligent / adaptive control algorithms, such as Optitune adaptive PID technology for optimizing turbine performance setup, and reverse - rotation sensing and alarm functions.
- Communication Capabilities
- Ethernet Communication: It has Ethernet communication ports for connectivity to plant DCS, service tools, and RemoteView operator control panels, enabling data exchange and remote monitoring and control.
- Other Communication Ports: There are also 4 CAN communication ports (1 Mbit, isolated), 1 RS - 232 / RS - 485 port (isolated), and 1 RS - 232 service port (isolated). It can also achieve Canopen actuator connectivity for Woodward varistroke actuators and DSLC - II power management networks.
- Input and Output Interfaces
- Speed Inputs: It includes two redundant speed inputs that can accept magnetic pickup units, eddy - current probes, or proximity probes.
- Analog Inputs and Outputs: There are 8 analog input channels (4 - 20 mA, with loop power) that can be configured for 27 different functions, and 6 analog output channels (4 - 20 mA). In addition, there are 2 actuator output channels (configurable 4 - 20 mA / 20 - 200 mA).
- Discrete Inputs and Outputs: It has 20 discrete input channels (with contact power) and 8 form - C relay contact outputs.
- Service and User Tools
- It has cyber - compliant password - enabled logins. The RemoteView (8928 - 5311) program enables virtual monitor and control from a remote workstation or mobile device. The Control Assistant service tool allows for easy configuration, saving, comparison, and viewing of settings and data logs.
- Operating Temperature: - 30 °C to + 70 °C (with display).
- Storage Temperature: - 30 °C to + 70 °C (recommended 0 °C to 40 °C).
- Vibration and Shock Resistance: It can withstand vibration of 8.2 grms (industrial skid - mount) and shock of 10 g, 3 times on each axis.
- Humidity: 5 % to 95 %, non - condensing.
- Ingress Rating / Installation: IP20, pollution degree 2, overvoltage category 3.
- EMC Emissions and Immunity: Complies with EN 61000 - 6 - 4 (heavy industrial) and IACS UR E10 (commercial marine) for emissions, and EN 61000 - 6 - 2 (heavy industrial) and IACS UR E10 (commercial marine) for immunity.
