Woodward 505 Digital Controller For steam turbineses

Drive proportional or integrated servo mechanism assemblies with single-pole execution up to 0-400 mA or dual-pole execution of +400 mA

The institution requires signals.

SPC comes with a user-friendly software interface program that allows users to configure the unit to the desired Settings.

Check the complete details of the types of actuators that SPC can connect to in the SPC manual. Below are 505 and

An example of how SPC can be applied to integrated servo mechanism valves. SPC can also handle many feedback devices

Transformation.

The actual power sensor is used to detect the actual power generated by the generator or the actual power flowing through the connecting lines.

Woodward's actual power sensor detects three-phase voltage and three-phase current, and compares the relationship between voltage and current of each phase.

And it generates a 4-20 mA output proportional to the actual power.

Woodward produces two types of actual power sensors. The first type of actual power sensor is designed for

Detect the power flow in only one direction (only 0 to +5 A CT current), and output a ratio of 4 to 20

mA signal. This type of actual power sensor is designed for and should be used to detect the power output of generators

Out. There are many different actual power sensors of this type. Some functions of the optional actual power sensor include

VAR detection, load distribution, 0-1 A CT current detection, and combinations of multiple functions. Please consult Wood.

Get the recommended actual power sensors suitable for your application from a Wards-certified distributor or Woodward factory.

The second type of actual power sensor produced by Woodward is designed to detect through busbar-to-busbar connection lines

Power flow. This actual power sensor (8272-726) detects A CT current ranging from -5 A to +5 A to allow it

Output power flows representing two directions. This actual power sensor provides a 4-20 mA power indication output

Output the signal, with 12 mA representing 0 power current. It is recommended to use this actual power sensor for detection only if it passes

The power current of a connecting line. It is required that this actual power sensor or equivalent equipment detect the input and output power of the power plant

Rate.

Woodward's actual power sensors have terminals labeled "Output" and terminals labeled "KW Read". “KW

The "read" terminal provides a 4-20 mA signal proportional to the actual power, which is used in parallel by the 505 controller

Compatible with it. Therefore, the actual power sensor labeled "Output" is for Woodward's 2301 type control

The device is designed and only compatible with it.

The output of the actual power sensor produced by Woodward has a 2.5Hz low-pass filter (with a delay of 400 ms)

It is used to filter out the high-frequency noise typically generated in the switch-type environment. Therefore, if another one is used

The power converter of this supplier should be verified to have similar filtering criteria before being applied together with 505.

Engine Generator Control Package/Load Distribution (EGCP-3 LS)

The Woodward EGCP-3 LS controller is a generator load-based microprocessor designed to work with Wood

Ward speed controllers and automatic voltage regulators are used together in three-phase AC generators. EGCP-3 LS is one

Synchronizer, one load controller, one dead busbar closure system, one VAR/PF controller, one overpass

The process controller, power and energy measurement, and protection relay are integrated into one.

The EGCP-3 LS has a keyboard and two 4-wire display panels on the chassis installed in the front cabinet. The display screen can

It is used to configure and set the controller according to the specific on-site requirements. The display screen can also be used for normal operation services to monitor

Depending on the operation and check the alarm data. All the functions performed on the front panel and all the parameters monitored can be accessed through three

Serial port obtained. These ports can be configured to use Woodward Watch Window software. This is one

An external HMI communicates with Modbus or Servlink DDE software.

The 505 configuration can be configured to use EGCP-3 LS only as a synchronizer, or as a synchronizer and load control

"Device. The EGCP-3 LS provides phase matching or slip frequency and is connected to the unit's automatic voltage regulator in parallel

Match the voltage before connection. It is connected to the 505 through a speed bias signal to control the generator frequency and phase

position. When configured to use EGCP-3 LS only as a synchronizer, 505 must be configured to be configured via analog input

Receive the EGCP-3 speed bias signal and enable this input through contact input or function keys.

When used as a synchronizer and load controller, EGCP-3 LS performs automatic synchronization in accordance with EGCP-3

The operation mode controller load. EGCP-3 LS can be set for basic load, load distribution, and remote load
