Abstract
Abstract The present invention relates to a gas storage power plant ( 1 ) with a gas store ( 8 ), a turbogroup ( 2 ) and a gas supply line ( 9 ) which leads from the gas store ( 8 ) to the turbogroup ( 2 ). A gas supply control device ( 12 ) is arranged in the gas supply line ( 9 ). So that a gas flow cam be provided, even in an emergency, the gas supply control device ( 12 ) has a main line ( 14 ) and a bypass line ( 19 ). The main line ( 14 ) forms a section of the gas supply line ( 9 ). In the main line ( 14 ) is arranged a main valve arrangement ( 15 ) which shuts off the main line ( 14 ) in an emergency. The bypass line ( 19 ) bypasses the main valve arrangement ( 15 ). In the bypass line ( 19 ) is arranged a bypass valve arrangement ( 20 ) which opens the bypass line ( 19 ) in an emergency.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
206 words
A gas supply control device for a gas storage power plant with at least one gas store, at least one turbogroup and at least one gas supply line which leads from the gas store to the turbogroup, the gas supply control device being provided for arrangement in the gas supply line, wherein the gas supply control device has a main line through which a flow is capable of passing and a bypass line through which a flow is capable of passing, the main line forming a section of the gas supply line in the gas supply control device arranged in the gas supply line, a main valve arrangement with at least one valve being arranged in the main line, including means for shutting off the main line in an emergency operating state of the main valve arrangement, the bypass line bypassing the main valve arrangement, and a bypass valve arrangement having at least one valve being arranged in the bypass line and including means for opening the bypass line in the emergency operating state of the main valve arrangement, the bypass valve arrangement having a quick-acting stop valve and including means for opening the bypass line in the emergency operating state of the main valve arrangement.
Claim 2
Dependent Claim
206 words
A gas supply control device for a gas storage power plant with at least one gas store, at least one turbogroup and at least one gas supply line which leads from the gas store to the turbogroup, the gas supply control device being provided for arrangement in the gas supply line, wherein the gas supply control device has a main line through which a flow is capable of passing and a bypass line through which a flow is capable of passing, the main line forming a section of the gas supply line in the gas supply control device arranged in the gas supply line, a main valve arrangement with at least one valve being arranged in the main line, including means for shutting off the main line in an emergency operating state of the main valve arrangement, the bypass line bypassing the main valve arrangement, and a bypass valve arrangement having at least one valve being arranged in the bypass line and including means for opening the bypass line in the emergency operating state of the main valve arrangement, the bypass valve arrangement having a quick-acting stop valve and including means for opening the bypass line in the emergency operating state of the main valve arrangement.
Claim 3
Dependent Claim
28 words
The gas supply control device as claimed in claim 1 , wherein the pressure regulating valve is arranged upstream of the quick-acting stop valve in the bypass line.
Claim 4
Dependent Claim
34 words
The gas supply control device as claimed in claim 1 , wherein the bypass valve arrangement includes means for shutting off the bypass line in a normal operating state of the main valve arrangement.
Claim 5
Dependent Claim
59 words
The gas supply control device as claimed in claim 1 , wherein the bypass line includes a gas volume stream which flows through the bypass line in the emergency operating state of the main valve arrangement is smaller than a gas volume stream which flows through the main line in the normal operating state of the main valve arrangement.
Claim 6
Dependent Claim
32 words
The gas supply control device as claimed in claim 1 , wherein the emergency operating state of the main valve arrangement arises when an emergency shutdown is carried out for the turbogroup.
Claim 7
Dependent Claim
45 words
The gas supply control device as claimed in claim 1 , wherein the bypass valve arrangement has a pressure regulating valve said pressure regulating valve opens the bypass line and including means for regulating pressure in the bypass line downstream of the pressure regulating valve.
Claim 8
Dependent Claim
38 words
The gas supply control device as claimed in claim 6 , wherein the pressure regulating valve is designed in such a way that it opens the bypass line in an emergency operating state of the pressure regulating valve.
Claim 9
Dependent Claim
