A combined control method of an Organic Rankine Cycle (ORC) plant, wherein the plant comprises at least a feed pump (1), a heat exchanger (2), an expansion turbine (3) and a condenser (5); the heat exchanger (2) and the turbine (3) being in fluid dynamic connection by means of at least one admission line (7) which is provided with an admission valve (AV); and the heat exchanger (2) and the condenser (5) being in fluid connection by means of at least one by-pass line (8) which is provided with a by-pass valve (BV). The Organic Rankine Cycle includes a step of feeding an organic working fluid, a step of heating and / or vaporization of the same working fluid, an expansion phase and a step of condensation of the same working fluid. The proposed method regulates the power supplied from plant determining an opening degree (%AV) of the admission valve (AV) as a function of a set point value of the required power and determining an opening degree of the by-pass valve (% BV) as a function of the opening degree (% AV) of the admission valve (AV), so that the total flow rate of the organic working fluid remains substantially constant during changing of the power supply output. |
