The invention discloses a distributed combined cooling and power supply system control method, which comprises the steps of: initializing system running state and system data, wherein the data system comprises preset system thermodynamic parameters; acquiring system running data; and conducting calculation according to the running data and the system data to obtain system thermodynamic parameters. If the system thermodynamic parameters do not satisfy the preset system thermodynamic parameters, the power of power generation equipment is adjusted. Otherwise, the power of the power generation equipment is maintained unchanged. The invention additionally discloses a distributed combined cooling and power supply system, which has the advantages that the automatic control can be realized, the control ability of the system is improved, the running efficiency of the system is improved and the economic benefit is improved.
Description
technical field [0001] The invention relates to the field of electric power supply control, in particular to a distributed combined cooling and power supply system. Background technique [0002] The distributed combined cooling and power system is a new type of energy supply mode. It is deployed at the user end, uses clean fuels, and can simultaneously provide electricity, cooling and other forms of energy.
