Abstract
The invention discloses a grouping running control method for multiple natural gas power generators. The grouping running control method comprises the following steps of (1) combining the multiple natural gas power generators with different powers into a machine set, and grouping a plurality of machine sets; (2) adjusting the power of the machine set with relatively low power when a load gradually changes, and maintaining high-efficiency power of the other machine sets; (3) closing or starting the power generator set with relatively low power when the load is descended or risen to a certain extent; and (4) enabling the machine sets which are started/stopped and of which the power is adjusted to work in turn, and maintaining the starting/stopping frequency and the running time of the natural gas power generators in each machine set to be same possibly.
Description
Technical field
The present invention relates to motor control technology field, particularly relate to a kind of multiple stage natural gas generator marshalling progress control method.
Background technology
Current Distribution of Natural formula energy project method of operation major part is grid-connected pattern of not surfing the Net, when load reduces, generating set power can only be reduced or carry out accumulation of energy, and reduce generating set power and can reduce generating efficiency, long-time low power run affects generating set service life, increases energy storage system and then can increase bigger cost.
Summary of the invention
In order to overcome problem of the prior art, the invention provides a kind of multiple stage natural gas generator marshalling progress control method.
In order to achieve the above object, a kind of multiple stage natural gas generator marshalling progress control method provided by the invention, comprise the following steps: (1) is in units of separate unit electromotor, multiple stage different capacity natural gas generator is combined into unit, multiple stage electromotor includes at least a more high-power and smaller power electromotor, and the watt level of smaller power electromotor is the half of relatively high power electromotor；(2) by the change of ammeter or electric energy meter detection load, when load variations value is less than the performance number of smaller power electromotor, regulating the power of smaller power unit, other units keep high efficiency power；(3) when load variations value exceedes the performance number of small power generator, the generating set of smaller power is turned off or on.
Wherein, further include steps of (4) start and stop and regulate the unit implementation rotation system of power, keeping the natural gas generator start-stop time in each unit as far as possible identical with the operation time；Start-stop time and the operation time of each electromotor are gathered by controller and record, before starter-generator, the generator running time of all stoppings is judged by controller, the electromotor selecting the operation time minimum starts, before stopping electromotor, judged the generator running time of all operations by control system, the electromotor selecting the operation time maximum stops.
The invention has the beneficial effects as follows: make generating set automatically run according to control strategy by control system, realize generating set according to fluctuation of load automatic start-stop and adjustment, when meeting burden requirement, unit overall efficiency is the highest, the service life of separate unit electromotor also increases, and generating set runs more reliable stable.
Detailed description of the invention
For the technical scheme making to present invention solves the technical problem that, adopting and the technique effect reached clearly, the present invention is described in further detail to adopt embodiment.It is understood that specific embodiment described herein is used only for explaining the present invention, but not limitation of the invention.
A kind of multiple stage natural gas generator marshalling progress control method that the present embodiment provides, comprise the following steps: (1) is in units of separate unit electromotor, multiple stage different capacity natural gas generator is combined into unit, multiple stage electromotor includes at least a more high-power and smaller power electromotor, and the watt level of smaller power electromotor is the half of relatively high power electromotor；(2) by the change of ammeter or electric energy meter detection load, when load variations value is less than the performance number of smaller power electromotor, regulating the power of smaller power unit, other units keep high efficiency power；(3) when load variations value exceedes the performance number of small power generator, the generating set of smaller power is turned off or on；(4) unit of start and stop and adjustment power carries out rotation system, keeps the natural gas generator start-stop time in each unit as far as possible identical with the operation time；Start-stop time and the operation time of each electromotor are gathered by controller and record, before starter-generator, the generator running time of all stoppings is judged by controller, the electromotor selecting the operation time minimum starts, before stopping electromotor, judged the generator running time of all operations by control system, the electromotor selecting the operation time maximum stops.
The present invention is used for multiple stage natural gas unit operation control strategy, do not surf the Net for multiple unit generations are grid-connected, and accumulation of energy capacity is less or situation without accumulation of energy, when load variations fluctuates, real-time tracking payload, by controlling single unit power and start and stop, reach to meet burden requirement, improve unit generation efficiency and service life simultaneously.
Last it is noted that various embodiments above is only in order to illustrate technical scheme, it is not intended to limit；Although the present invention being described in detail with reference to foregoing embodiments, it will be understood by those within the art that: the technical scheme described in foregoing embodiments is modified by it, or wherein some or all of technical characteristic is carried out equivalent replacement, does not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
