Description
Technical field
The present invention relates to steam-electric power control technical field, be specially a kind of steam-electric power machine controller.
Background technology
During steam-electric power, because the parameter such as steam flow, temperature usually instability, amplitude of variation are big,
In addition the opening of load equipment, the changed power that operation can cause electrizer output such as stop, increase output
The difficulty of utility power quality control.The change of any of the above described a kind of factor all can cause generator output electric energy not
Stable, reality is typically two or more factors and changes simultaneously and interact, then make generator
Output electric energy is more unstable.For this situation, existing solution is: by detection generator
Rotating speed the aperture controlling steam flow control valve, constituted closed loop regulating loop with this, thus reached stable
Output electric energy purpose.
But this generating equipment controller of actually used middle discovery has the disadvantage in that
(1) thermal energy conversion efficiency is low.Main reason is that controller noted above uses unitary variant control structure,
For example: detect generator speed by timing sampling, utilize the regulation algorithms such as PID, regulate steam stream
The aperture of adjustable valve, and then the gas flow of control entrance steam power machine.But what steam was contained
Interior can be not only related to flow, also related to temperature, pressure and other parameters, therefore unitary variant regulation side
Method, it is impossible to preferably internal steam work is converted into electric energy, thus results in its thermal energy conversion efficiency low.
(2) operation inconvenience.It is mainly manifested in various controls after debugging completes in program for this controller
Parameter solidifies relatively, and once steam characteristics fluctuation is beyond originally presetting scope, by operator again
The difficulty of modification or debugging is big, is typically only capable to be carried out field adjustable by professional；Respective controllers can set
Meter operation button, but because it lacks related interactive means so that layman is in Correction and Control parameter
When, it is impossible to this parameter modification of Accurate Prediction and the control effect that changes, do not reach preferably control purpose,
Equipment can be caused what is more cannot normally to work or cause accident.
(3) management inconvenience.It is mainly manifested in: this controller is mainly for separate unit generating set, and independent
Work has isolatism, and therefore unmanned truly is difficult to realize, once breaks down,
Even if controller itself has self-protection function, but owing to its duty cannot be by miscellaneous equipment or prison
Control room understands, therefore can cause imponderable infringement to relative equipment, and this point especially embodies not
On the load equipment of power-off, and can use what pipeline steam be depressured by this unit to relate to steam for working
On the relative production process of medium or equipment.
(4) inconvenience is safeguarded.Be mainly manifested in due to this controller design when just for fixing control
Object, functionally may can reserve control input and output point more than needed at some, but its reserved function point is also
There is specific aim, be therefore not easy to follow-up some instrument increasing newly for strengthening the output quality of power supply or changing
The equipment such as instruments and meters or executing agency, thus the needs improving follow-up function and optimizing cannot be met；Separately
On the one hand, make controller according to embedded system and can solidify on circuit boards because of device so that electricity occurs
During the fault of road, being unfavorable for Quick overhaul, the production to factory impacts.
(5) it is unfavorable for the intelligentized updating in factory's future.Owing to this controller can not be to control system of central authorities
System sends state information parameters, also cannot accept the control instruction that central control system sends, this function
On upper and lower " government decree " obstructed, the obstacle of factory of the future intelligentized updating will be become, cause economically
Loss.
