Abstract
The study is devoted to the development of object-oriented analysis for an automated control system to enhance the capabilities of manoeuvring a nuclear power unit with the WWER-1000 by switching the power control programmes of the NPP during its operation. The research was conducted to check whether the reactor unit was stable or not at the in-operation transition mode. According to the simulation results, control programmes during the operation of the nuclear power plant can be switched. The reactor unit remains in a stable state, which is evidenced by the values of the axial offset as a quantitative measure of the reactor stability. By using the suggestion and manoeuvring not only the capacity of the nuclear power plant but also the control programmes, it is possible to bring the consumption schedule of electric power to conformity with the schedule of electric power generation without affecting the safety of the nuclear power plant in operation.
Highlights
Using a known control programme [1], manoeuvring capacity may be achieved, which brings the consumption schedule of electric power to conformity with the schedule of electric power generation [2]
It will allow nuclear power plants operation at the manoeuvring capacity and even manoeuvring power control programmes of nuclear power plants (NPP) with the water-water energy reactor (WWER)-1000 in operation depending on the selected factors that influence the switching
The main disadvantage was absence of studying control programme modes to explain why power declined with one control programme in use and why it increased while another programme was used
Summary
Using a known control programme [1], manoeuvring capacity may be achieved, which brings the consumption schedule of electric power to conformity with the schedule of electric power generation [2]. It is impossible to reach full compliance due to an unexpected accident or an inclusion of new customers in an electric network. An adaptation of existing power units to new specific working conditions becomes of current importance. It will allow nuclear power plants operation at the manoeuvring capacity and even manoeuvring power control programmes of nuclear power plants (NPP) with the WWER-1000 in operation depending on the selected factors that influence the switching
