Coordinated control system and method for an organic working medium power cycle power generation system

Abstract

The invention discloses a coordinated control system and method of an organic working medium power cycle power generation system. The system comprises a working medium pump, an evaporator, a turbine and a condenser connected in sequence to form a working medium side circulating channel; an adjusting valve is arranged between the evaporator and the turbine; a pressure measuring transducer and a temperature measuring transducer are arranged between the evaporator and the adjusting valve; the turbine is coaxially connected with a generator; a rotating speed measuring transducer is arranged between the turbine and the generator; the condenser is connected with a cooling water input pipe; the evaporator is connected with the organic working medium power cycle power generation system through a pipe; and the working medium pump, the pressure measuring transducer, the temperature measuring transducer, the adjusting valve and the rotating speed measuring transducer are connected with a controller side by side to form the coordinated control system. The technical guarantee is provided for safety, stability and high efficiency in actual operation of the system; the application popularizationof the organic working medium power cycle power generation system to the low-grade heat source recycling field is facilitated; and the energy utilization efficiency is improved.

Description

technical field [0001] The invention belongs to the technical fields of low-grade heat source, industrial waste heat recovery and utilization, power generation coordination control and power engineering, and specifically relates to a coordination control system and method for an organic working medium power cycle power generation system. Background technique [0002] With the rapid development of the global economy, energy consumption is increasing day by day. Low-grade heat sources such as solar energy, geothermal energy, and a large amount of low-temperature waste heat generated by industrial activities have not been effectively and fully utilized due to the difficulty of recovery and high cost. A large amount of energy is directly waste. The organic working fluid power cycle power generation system can efficiently convert low-grade heat sources into electrical energy, which is of great significance to reducing energy consumption and promoting sustainable social developmen...
