Poland - Steam turbines

Description

The subject of the contract is: renovation of turbine block no. 7 in the scope of: parts of WP, SP, NP, generator, condenser (replacement of 50% of pipes), control system and turbine steam and oil pipelines. The renovation will result in an increase in turbine efficiency (reduction of specific heat consumption by at least 100 kJ/kWh), measured at the nominal value of steam flowDo turbine (650 t/h fresh steam), the values obtained during warranty measurements will be converted into nominal working conditions of the turbine. The detailed scope of work is contained in Annexes 1a to the ToR. The subject of the contract is the turnkey execution of the task entitled "Replacement of turbine set no. 7 armature in the Lower Odra Power Plant" consisting in the design, execution, delivery, installation, commissioning and commissioning of turbine set no. 7 in the Lower Odra Power Plant. The detailed scope of work is contained in Annexes 1b to the ToR. The subject of the contract is preparation for UDT inspection and repair of the 7ZZZ tank, 7XW1÷3 diesel heaters, 7XN3÷5, 7XA÷B low-pressure heaters and 7CT, 7CU coolers in the Lower Odra Power Plant. The detailed scope of work is contained in Annexes 1c to the ToR. The subject matter of the contract is the renovation of the electrical and control and measurement part of the power unit, which includes: - Rafako type boiler: OP650-050,- steam turbine by Zamech-Elbląg type 13K215, single-shaft, three-hull, condensing, with 7 unregulated outlets,- Dolmel generator, type: GTHW-230,- generator switch by ABB type: HEC3,- block transformer by Elta, type: TFBb 24000000/400.Boiler technological protection systems are implemented in the ABB Procontrol P13 system, boiler regulation is implemented in the ABB Procontrol P14 system.The turbine protection systems are implemented in the ABB Procontrol P13 system, the electro-hydraulic turbine regulator is implemented in the Unimat system, the reactive power control of the generator is performed by a digital voltage regulator ETEF200C generator manufactured by Energotest Gliwice.The unit CZAZ-GT produced by ZEG Energetyka is responsible for the Electric Power Safety Automatics of the unit (generator - transformer). It consists of the segments CZAZ-GT-A and CZAZ-GT-B responsible for proper reaction to all types of disturbances and abnormal operating conditions. Power output from unit no. 7 in the Lower Oder Power Plant is carried out by 400 kV line of the length of 3 km to SE Krajnik.
