Westinghouse Steam Turbine Manual

Posted By admin On 21.04.21

I claim:

The Siemens/Westinghouse W501D gas turbine was developed jointly by Westinghouse Electric and Fiat. These huge single-shaft units generally operate at 3600 rpm to generate 60-Hz power. Special attention is given to design and development of cooling systems for the hot-section components, both during transient conditions and normal operation. Steam from boiler 10 is supplied via respective throttle valves TV1 and TV2 to steam chests 30 and 31 and then to high pressure turbine 34 by way of the governor valves, with the odd-numbered governor valves GV1, GV3 and GV5 being integral with steam chest 30 and the even-numbered governor valves GV2, GV4 and GV6 being integral with steam chest 31.

1. A valve test system for a steam turbine having at least a throttle valve and a plurality of governor valves for controlling steam admission to the turbine, comprising:

(a) calculator means (70) for generating a plurality of individual governor valve position demand signals;

(b) a plurality of individual valve position control circuits (41) each for governing operation of a respective one of said governor valves in response to a respective input valve position demand signal;

(d) means for providing a valve test signal (86);

(e) first means (80) for distributing said reference signal among all of said governor valve position demand signals;

(f) second means (88) for distributing said valve test signal among only selected ones of said governor valve position demand signals;

(g) means for subtracting (82/83) the distributed signals of said second means from those of said first means.

2. Apparatus according to claim 1, which includes:

(a) means for adding (78) said valve test signal to said reference signal whereby said valve test signal is distributed by said first means among all of said governor valve position demand signals.

3. Apparatus according to claim 1 wherein:

(a) said turbine includes a plurality of steam chests (30/31) for delivering steam to said turbine;

(b) each said steam chest having a plurality of governor valves (GV1, GV3, GV5/GV2, GV4, GV6) and only one throttle valve (TV1/TV2).

4. Apparatus according to claim 3 wherein during a valve test process:

(a) the odd numbered governor valves are simultaneously closed while the even numbered governor valves are simultaneously opened.

5. Apparatus according to claim 3 wheren during a valve test process:

(a) the odd numbered governor valves are simultaneously opened while the even numbered governor valves are simultaneously closed.

6. Apparatus according to claim 1 wherein:

(a) said valve test signal is a ramp signal.

7. Apparatus according to claim 1 wherein:

(a) said calculator means is operable to modify the signals provided by said first means to as to compensate for non linear valve characteristics.
