Abstract
The invention belongs to the technical field of energy and power, in particular to an unattended operation type monitoring system and method for organic Rankine cycle isolated network power generation. According to the unattended operation type monitoring system and method for organic Rankine cycle isolated network power generation, automation control of the monitoring system for organic Rankine cycle isolated network power generation and system malfunction automatic processing are achieved. The monitoring system comprises a flowmeter, pressure sensors, temperature sensors, a working medium pump, an evaporator, an electric three-way valve, an expansion machine, a power generator, a condenser, a heat source circuit, a cooling circuit, a touch screen, a PLC unit, a working medium pump frequency converter, a relay, a warner and a multifunctional electrodynamic meter. Through real-time state monitoring of a unit, under instable heat-source and cold-source fluctuation, stabile, reliable and efficient operation of a waste heat power generation system is achieved. According to the unattended operation type monitoring system and method, while good self-adaption is achieved, automatic adjusting can be conducted when the system malfunctions, and unattended operation of an isolated network power generation system is achieved.
Description
Technical field [0001] The invention belongs to the technical field of energy and power, and in particular relates to an unattended organic Rankine cycle isolated grid power generation monitoring system and method. Background technique [0002] Organic Rankine Cycle (ORC) is a technology that can effectively utilize medium and low temperature thermal energy (such as waste heat, solar energy, geothermal energy, etc.). The traditional steam Rankine cycle uses water as the working medium and the boiling point of water is high. If low-temperature waste heat is used, it is not easy to reach and maintain the superheated state due to the large specific volume of steam, which makes the cycle efficiency very low, and even the cycle cannot be completed. The organic Rankine cycle uses a low boiling point organic working fluid. Due to the low boiling point of the organic working fluid, it is easy to overheat and easily generate high pressure steam. In addition, the organic Rankine cycle equi...
