FUNCTIONAL DESCRIPTION:

IS220YTURS1A is a Primary Turbine Protection I/O Module manufactured and designed by General Electric and is part of the Mark VIeS Series used in GE Distributed Turbine Control Systems. The Primary Turbine Protection (YTURS1A) pack provides the electrical interface between one or two IONets and a primary protection terminal board. YTUR plugs into the TTUR terminal board and handles four-speed sensor inputs, bus and generator voltage inputs, shaft voltage and current signals, eight flame sensors, and outputs to the main breaker. Safety-certified protection includes:

• Speed An interface is provided for up to four passive, magnetic speed inputs with a frequency range of 2 to 20,000 Hz.

• Flame Detection Voltage pulses above 2.5 V generate a logic high; the pulse rate is measured in a counter over a configurable time (multiple of 40 ms).

• ETD TRPx contains relays for interface with the electrical trip devices (ETD).

YTURS1A is compatible with the TTUR and TRPA terminal boards. As an alternative to TTUR, three YTUR packs can be plugged directly into a TRPA terminal board. In this arrangement, TRPA holds four-speed inputs per YTUR or alternately fans the first four inputs to all three YTURs. TRPA provides two solid-state primary trip relays. This arrangement does not support bus and generator voltage inputs, shaft voltage or current signals, flame sensors, or main breaker output. The YTUR flame detection has been designed and analyzed with the safe state being the presence of flame. Flame sensing is not intended for applications where detected flame is the unsafe state.

YTUR TEST PROCEDURES:

Speed inputs are tested when input signals are varied and compared to the reference signal. Flame detector (Gieger-Muller) inputs are tested when the presence of flame is observed. E-Stop input is tested when actuated and PTRs are observed to drop out. When power (or the communications cable) is removed from one I/O pack in a hardware fault-tolerant channel, the system should maintain the required output.

Configurable items in the YTUR pack are identified in this test plan by including (CFG) at the end of the name of the item. Any configurable items that must be set for a particular test are defined in the detailed test instructions below. If a setting is not given for a configurable item, it is not relevant to that test.

• Unless otherwise noted, verify that there are no diagnostics faults on the YTUR pack under test before performing each test case.
• Any diagnostic fault(s) that are expected to occur as a result of performing a test case are detailed in the acceptance criteria for the test case.
• If additional diagnostics faults are generated that are not detailed in the acceptance criteria, they must be fully explained before acceptance of the test.

FREQUENTLY ASKED QUESTIONS:

What is a Primary Turbine Protection I/O Module?

A Primary Turbine Protection I/O Module is an integral component in turbine control systems designed to manage and monitor turbine safety parameters. It ensures real-time data acquisition and triggers protective measures in case of system anomalies or operational risks.

How does the module ensure turbine safety?

The module continuously monitors input signals from sensors and actuators. If any parameter exceeds its predefined safety threshold, it activates protective mechanisms such as shutdown signals to prevent turbine damage or accidents.

What is the difference between primary and backup protection modules?

Primary protection modules handle the main turbine safety functions, while backup (or secondary) modules serve as fail-safe. Backup modules activate only if the primary system fails, ensuring redundancy and continuous protection.
