Diesel gen-sets for nuclear, thermal and hydro power plants

According the regulation, the current power supply of the key devices and control systems of nuclear, thermal and hydro power plants from their own generation has to be reserved by outside power via grid lines, fixed reserve diesel gen-sets and emergency mobile gen-sets. In case of accident on NPP, TPP or HPP when it isn’t possible to meet own power demand from own power generation, the fixed reserve gen-sets have to provide it (figure 1), and in case of their fall the situation has to be solved by mobile emergency gen-sets connected to the crucial points of the power demand (figure 2).

The key systems of NPP, TPP and HPP are the circulation pumps, water gates drivers, ventilation pumps and control devices. They have to be supplied with the power even in case of destruction of own power generation facilities of nuclear, thermo and hydro power plants in the result of natural, technical or other kind of calamities. To meet their power demand in case of emergency VETZ develops and manufactures special gen-sets with prime power of 625kVA-10000kVA with the voltage of 400V (figure 3) and 6000V-24000V AC (figure 4) and 220V of DC (figure 5). The task of the gen-sets in case of emergency is to prevent the destruction of the nuclear reactor or the dumb or the boilers or other crucial equipment of NPP, TPP and HPP.

VETZ manufacturing of the gen-sets for NPP, TPP and HPP is based on amendment under special requirements of the general design of:

so as if necessary on the development of the innovative design of the gen-sets (figure 10).

The amendment of the regular gen-sets and the development of the innovative design for the gen-sets of NPP, TPP and HPP applications on VETZ are ruled by following maximas:

  1. The throughful copliance to the requirements of the customer.
  2. The special VETZ-made design of the gen-sets and their main parts.
  3. The attentive choice of best components for the gen-sets on domestic and international market.
  4. The full-scale test program for the gen-sets and their key parts on VETZ.
  5. Special licencies and sertificates for the gen-sets and their components.

VETZ manufactures the gen-sets for NPP, TPP and HPP applications of the following designs:

The throughful copliance of VETZ gen-sets for NPP, TPP and HPP to the requirements of the customer is achieved by detailed research of the gen-set tasked performance in the installation case: the specifics of the load and the load charge, the requirements for the variety of power (medium voltage, low voltage, AC or DC atc.), the necessity of the parallel work of the gen-sets or synchronization with the grid, the requirement for the continues work without the fuel refill, the demands of the self-control, the remote control or the integration in the central control of NPP, TPP, HPP, the demands of the equipment and staff protections, environmental conditions of the installation, the requirements for the gen-set mobility and so on (figure 17).

In initial stage of the manufacturing VETZ negotiates with the customer or the final user main technical parameters of the gen-sets, main spare parts, the test programs as for VETZ testing bench as for onsite tests. If it is necessary VETZ negotiate the design of the gen-sets with the body responsible for the general design of NPP, TPP or HPP or for the design of their reserve and emergency power supply (figure 18).
