  • 用C51實(shí)現(xiàn)無功補(bǔ)償中電容組循環(huán)投切的算法

    介紹了用單片機(jī)C 語言實(shí)現(xiàn)無功補(bǔ)償中電容組循環(huán)投切的基本原理和算法,并舉例說明。關(guān)鍵詞:循環(huán)投切;C51;無功補(bǔ)償中圖分類號: TM76 文獻(xiàn)標(biāo)識(shí)碼: BAbstract: This paper introduces the aplication of C51 in the controlling of capacitorsuits cycle powered to be on and off in reactive compensation.it illustrate thefondamental principle and algorithm with example.Key words: cycle powered to be on and off; C51; reactive compensation 為提高功率因數(shù),往往采用補(bǔ)償電容的方法來實(shí)現(xiàn)。而電容器的容量是由實(shí)時(shí)功率因數(shù)與標(biāo)準(zhǔn)值進(jìn)行比較來決定的,實(shí)時(shí)功率因數(shù)小于標(biāo)準(zhǔn)值時(shí),需投入電容組,實(shí)時(shí)功率因數(shù)大于標(biāo)準(zhǔn)值時(shí),則需切除電容組。投切方式的不合理,會(huì)對電容器造成損壞,現(xiàn)有的控制器多采用“順序投切”方式,在這種投切方式下排序在前的電容器組,先投后切;而后面的卻后投先切。這不僅使處于前面的電容組經(jīng)常處于運(yùn)行狀態(tài),積累熱量不易散失,影響其使用壽命,而且使后面的投切開關(guān)經(jīng)常動(dòng)作,同樣減少壽命。合理的投切方式應(yīng)為“循環(huán)投切”。這種投切方式使先投入的運(yùn)行的電容組先退出,后投的后切除,從而使各組電容及投切開關(guān)使用機(jī)率均等,降低了電容組的平均運(yùn)行溫度,減少了投切開關(guān)的動(dòng)作次數(shù),延長了其使用壽命。

  • Input Signal Rise and Fall Tim

    All inputs of the C16x family have Schmitt-Trigger input characteristics. These Schmitt-Triggers are intended to always provide proper internal low and high levels, even if anundefined voltage level (between TTL-VIL and TTL-VIH) is externally applied to the pin.The hysteresis of these inputs, however, is very small, and can not be properly used in anapplication to suppress signal noise, and to shape slow rising/falling input transitions.Thus, it must be taken care that rising/falling input signals pass the undefined area of theTTL-specification between VIL and VIH with a sufficient rise/fall time, as generally usualand specified for TTL components (e.g. 74LS series: gates 1V/us, clock inputs 20V/us).The effect of the implemented Schmitt-Trigger is that even if the input signal remains inthe undefined area, well defined low/high levels are generated internally. Note that allinput signals are evaluated at specific sample points (depending on the input and theperipheral function connected to it), at that signal transitions are detected if twoconsecutive samples show different levels. Thus, only the current level of an input signalat these sample points is relevant, that means, the necessary rise/fall times of the inputsignal is only dependant on the sample rate, that is the distance in time between twoconsecutive evaluation time points. If an input signal, for instance, is sampled throughsoftware every 10us, it is irrelevant, which input level would be seen between thesamples. Thus, it would be allowable for the signal to take 10us to pass through theundefined area. Due to the sample rate of 10us, it is assured that only one sample canoccur while the signal is within the undefined area, and no incorrect transition will bedetected. For inputs which are connected to a peripheral function, e.g. capture inputs, thesample rate is determined by the clock cycle of the peripheral unit. In the case of theCAPCOM unit this means a sample rate of 400ns @ 20MHz CPU clock. This requiresinput signals to pass through the undefined area within these 400ns in order to avoidmultiple capture events.For input signals, which do not provide the required rise/fall times, external circuitry mustbe used to shape the signal transitions.In the attached diagram, the effect of the sample rate is shown. The numbers 1 to 5 in thediagram represent possible sample points. Waveform a) shows the result if the inputsignal transition time through the undefined TTL-level area is less than the time distancebetween the sample points (sampling at 1, 2, 3, and 4). Waveform b) can be the result ifthe sampling is performed more than once within the undefined area (sampling at 1, 2, 5,3, and 4).Sample points:1. Evaluation of the signal clearly results in a low level2. Either a low or a high level can be sampled here. If low is sampled, no transition willbe detected. If the sample results in a high level, a transition is detected, and anappropriate action (e.g. capture) might take place.3. Evaluation here clearly results in a high level. If the previous sample 2) had alreadydetected a high, there is no change. If the previous sample 2) showed a low, atransition from low to high is detected now.
