同步裝置主要用于發(fā)電廠或工業(yè)

自備發(fā)電廠，在島上運(yùn)行時(shí)，發(fā)電機(jī)必須與干線并聯(lián)，與公共網(wǎng)絡(luò)中的干線或與配電系統(tǒng)并聯(lián)。

只有當(dāng)兩個(gè)電壓至少接近時(shí)，才能打開電源開關(guān)

同步（同相）。如果不滿足此條件，可能會(huì)發(fā)生操作

接線故障、發(fā)電機(jī)過載，或在極端情況下造成損壞

發(fā)電機(jī)。

同步器? 5確保安全可靠地執(zhí)行這些功能

手動(dòng)控制并聯(lián)開關(guān)的監(jiān)控成員，或作為一個(gè)獨(dú)立的、全自動(dòng)的

同步單元。

同步和并行切換過程可分為以下幾個(gè)塊：

測量

電壓（振幅）ΔU、滑差（頻率差）“s”和相位差值

角度α是評估并聯(lián)開關(guān)所必需的，由兩個(gè)組成

測量信號(hào)U1和U2（見下圖）。

匹配

電壓和頻率調(diào)節(jié)功能通過向電壓調(diào)節(jié)器或渦輪機(jī)控制器傳輸控制脈沖來減少電壓差ΔU和滑差“s”。

并行條件的監(jiān)測

此功能將當(dāng)前值與其設(shè)置的最大值進(jìn)行比較，如果

同時(shí)滿足所有條件，釋放并行切換（CHK RELEASE）。

命令生成

命令生成塊計(jì)算必要的超前角av

提前發(fā)送并行交換（ORDER），以消除由

開關(guān)的時(shí)間，并確保主觸點(diǎn)在相位的精確時(shí)刻接通

比賽。如果角度α在儀器釋放的同時(shí)達(dá)到α值

并行切換（CHK RELEASE），命令被發(fā)送去激活。在同步條件下（即。

在一段調(diào)整期內(nèi)永久滿足并聯(lián)切換條件時(shí)的條件

監(jiān)測時(shí)間“tsup”），也在不考慮前向角度的情況下發(fā)送命令。

Synchronization units are mainly used in power plants or industrial

self-generating power plants, where generators must be connected in parallel with mains in island operation, with mains in the public network or with distribution systems.

The power switch can only be switched on if both voltages are at least approximately

synchronous (in phase alignment). If this condition is not met, operation may occur

faults in the wiring, overloading the generator, or in extreme cases to damage

the generator.

SYNCHROTACT ?? 5 ensures safe and reliable implementation of these functions either as

monitoring member of manually controlled parallel switching, or as an independent, fully automatic

Synchronization unit.

The synchronization and parallel switching process can be divided into the following blocks:

Measuring

Voltage (amplitude) ΔU, slip (frequency difference) "s" and phase difference values

angle α, which are necessary for the evaluation of parallel switching, are made of two

measured signals U1 and U2 (see figure below).

Matching

The voltage and frequency adjustment functions reduce the voltage difference ΔUand slip "s" by transmitting control pulses to the voltage regulator or turbine controller.

Monitoring of parallel conditions

This function compares the current values with their set maximum values and if

all conditions are met at the same time, releases parallel switching (CHK RELEASE).

Command generation

The command generation block calculates the necessary lead angle av, by which the command for

parallel switching (ORDER) sent earlier to eliminate delay caused by

the time of the switch and to ensure that the main contacts switch on at the exact moment of the phase

matches. If angle α reaches the value of α at the same time that the instrument releases

Parallel switching (CHK RELEASE), the command is sent deactivated. In synchronous conditions (i.e.

condition when conditions for parallel switching are permanently met for a period of adjustment

the monitoring time 'tsup') the command is also sent without taking into account the forward angle.
