Problems solved by technology

Power oversupply forces utilities to rely on more polluting and less efficient energy sources to meet peak demand, rather than simply redistributing surplus power from low-demand markets to high-demand markets, thereby lead to lower energy efficiency

Abstract

The invention aims to provide a distributed-type non-tracking solar expander power generation and poly-generation system. A solar non-tracking collecting system (8) is connected with an evaporator (1) or a heat accumulator (5); the evaporator (1) is arranged in the solar non-tracking collecting system or the heat accumulator, wherein the evaporator (1), a fluid generator (2), a condenser (3) and a working medium circulating pump are connected in series to form an enclosed circulating cavity; a power generating working medium is enclosed into the enclosed circulating cavity; the power generating working medium in the evaporator (1) is heated by the heat energy which is collected by the solar non-tracking collecting system (8); the power generating working medium converts the heat energy which is collected by solar energy into power energy through the fluid generator (2); the power generating working medium enters the condenser (3) and is condensed after passing through the fluid generator; and the condensed power generating working medium is sent into the evaporator (1) again through the working medium circulating pump and is evaporated, thus the circulating power generation is realized.

Description

technical field [0001] The invention relates to solar power generation, in particular to a system for power generation and polygeneration with heat energy collected by a distributed solar non-tracking collection system. Background technique [0002] The existing power generation technology mainly uses steam as the working medium to generate electricity, that is, steam thermal power generation limited by the Carnot cycle through the principle of heat engine. The main working medium is water. The nozzle is set on the stator without movement, and the blades are set on On the rotor, the steam injected by the nozzle pushes the blades to rotate and generate electricity. [0003] The Rankine cycle (ORC) generator set using low-temperature organic matter is suitable for low-temperature heat sources and small-scale power generation, but it is still a heat engine of the Carnot cycle, which is to miniaturize the existing large-scale steam power generation equipment. The same as the la...
