Abstract

The invention discloses a method for undisturbed switching between double power sources of a hydraulic station of a refuse incinerator. A plurality of super-capacitors are used as energy storage elements. The problem that during switching by a commonly-used switch for the double power sources, continuous control power cannot be output is solved. By means of a power failure detection signal of double groups of mains supply, a corresponding control program is designed in the PLC control system, and heavy-load starting or acceleration of a motor is avoided in a power source switching period; according to actual power source voltage class demand, a modularized equalization circuit is used for guaranteeing that the super-capacitors which are connected in series are charged equally, and the service life of the super-capacitors is prolonged.

Description

Technical field

[0001] The invention belongs to the technical field of garbage power generation control, and relates to a method for undisturbed switching of dual power sources of a hydraulic station of a garbage incinerator. Background technique

[0002] As the contradiction between increasing garbage and limited processing capacity continues to intensify, power generation through garbage incineration is the main method to achieve garbage reduction, recycling and harmlessness. Among various waste incineration technologies, mechanical grate furnace incineration technology will be the mainstream incineration technology for domestic waste at present and in the future. The garbage enters the incinerator through the movement of the feeder, and then the full mixing and combustion of the garbage and the air are realized through the reciprocating motion of the grate. With the help of the boiler and the turbo generator, the conversion of chemical energy → thermal energy → electric energy...

Examples

Embodiment Construction

[0026] The technical scheme of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0027] A non-disturbed switching method for dual power supplies of a hydraulic station of a garbage incinerator is characterized in that it comprises the following steps:

[0028] Step 1: Estimate the load, select the dual power switch

[0029] The main electrical equipment of the waste incineration power generation hydraulic station (oil station) includes two main oil pump motors, two cooling pumps and a heater, a DC power supply and a control system. The main oil pump motor and the cooling pump motor both work in one-use and one-backup mode. Therefore, only the power consumption of one main oil pump and one cooling pump is considered.

[0030] The total power of the power supply system is as follows:

[0031] P All = k p ( P OilPump + P CoolPump + P Heater + P DC + P ConSys...
