Повышение эффективности информационных обменов подсистемы учета потребления электроэнергии в интегрированных системах диспетчерского управления

Abstract

Предложены подходы к совершенствованию информационных обменов подсистемы учета потребления электроэнергии в интегрированных системах диспетчерского управления, основанные на разделении информационного потока на оперативный и неоперативный контур. Для передачи оперативной информации используются данные от числоимпульсных выходов счетчиков. Информационное сообщение, включающее коды числа импульсов от 8 -16 счетчиков, по методу нарастающего итога (без обнуления накопителей импульсов) передается с циклом в одну три минуты. Для повышения достоверности данных, полученных по числоимпульсным каналам, используется трехкратный ввод сигналов, после чего по принципу “два или три из трех” идентифицируется реальный сигнал, и принятая информация заносится в индивидуальные для каждого счетчика накопители импульсов. Кодовые данные по интерфейсу “токовая петля” являются контрольными и могут передаваться достаточно редко. “Токовая петля” позволяет передавать не только данные об измеренной энергии и мощности, но и многочисленную дополнительную информацию, например: время и дату начала отключения питания или фазы, наличие тарифных зон и их распределение по суткам, данные самодиагностики счетчика. Разделение информации на оперативную и неоперативную составляющие повышает эффективность использования аппаратуры и каналов связи.

The article suggests the approaches to improve information exchanges accounting subsystem power consumption in integrated systems supervisory control, based on the separation of the flow of information on the operational and non-operational path. For transmission of operational information using data from unit-counting output counters. Information message, including the number of pulses codes 8-16 meters cumulative sum method (without zeroing drive pulses) is transmitted in one cycle three minutes. To improve the reliability of data obtained by unit-counting channels, input signal is used three times, after which the principle of "two or three of the three" identified the real signal and the received information is stored in individual drives for each counter pulses. Coded data on the interface "current loop" are control and may be transmitted infrequently. "Current loop" not only allows to transfer data on the measured energy and power, but also numerous additional information, such as time and date of the start of a power outage or phase, the presence of rate zones and their distribution in the day, self-diagnosis of the counter. Information sharing for operational and non-operational components increases the efficiency of equipment and communication channels.
