Problems solved by technology
The equipment consumes power in the three states of running, standby, and shutdown, but does not generate value in the standby and shutdown states
[0003] In the prior art, since it is impossible to know the status of each equipment in the power system, when the equipment works for a long time in the standby or shutdown state, it will cause waste of electric energy

The invention discloses a state analysis method for power system equipment. The state analysis method includes acquiring actual power and electricity consumption of the power system equipment according to a preset acquisition interval, and determining acquisition time; acquiring power threshold values, which are stored in an equipment power table, of three states of the power system equipment; comparing the actual power with the power threshold values, and determining a current state of the power system equipment according to a comparison result; and accumulating the acquired electricity consumption of the power system equipment in the three states to respectively obtain electricity consumption of the power system equipment in unit time, the proportion of the electricity consumption of the power system equipment in each state and the proportion of duration of each state of the power system equipment. Electricity is reasonably consumed by an enterprise under guidance of the electricity consumption of the equipment in the three states, the proportion of the electricity consumption of the power system equipment in each state and the proportion of duration of each state of the power system equipment which are obtained by the aid of the state analysis method for the power system equipment, and electric energy waste is reduced.
Description
technical field [0001] The present invention relates to the technical field of power systems, and more specifically, to a state analysis method and system for power system equipment. Background technique [0002] Power system equipment includes three states: running, standby, and shutdown. The equipment consumes power in the three states of operation, standby, and shutdown, but does not generate value in the standby and shutdown states. [0003] In the prior art, since the status of each device in the power system cannot be known, when the device works in a standby or shutdown state for a long time, electric energy will be wasted. Contents of the invention [0004] In view of this, the present invention provides a state analysis method and system for power system equipment to monitor power consumption of power system equipment in different states, guide enterprises to use electricity reasonably, and reduce waste of electric energy. [0005] In order to achieve the above ...
