Abstract

Monitoring of gas distribution networks (GDN) performances is the necessary condition for providing GDN reliability and safety in exploitation. The telemetry systems which transmit the collected data to control manager in accordance with GPRS technology and contain communication bus working on the basis of GSM standard are widely used for such a purpose. This approach allows successful controlling the performances of the various plants with distributed location. However the problem of the choice of a time period at which the collected data should be sent to control manager is still open. On one hand, it is necessary to minimize the usage of wireless traffic; on other hand, we have to make provision for being informed in proper time of the dangerous tendencies in change of GDN parameters in order to predict the accidents. The paper analyzes that problem. The authors propose to perform correction of the initially set time period of updating the information on GDN performances taking into account the results of prognosis of tendencies in a change of the controlled parameters on the basis of Holt’s forecasting algorithm.

Реализация мониторинга состояния газораспределительных сетей (ГС) является необходимым условием обеспечения их надежности и безопасности эксплуатации. Для этих целей широко используются системы телеметрии, которые осуществляют передачу собранных данных диспетчеру в соответствии с технологией GPRS по каналу связи, работающему на базе стандарта GSM. Такой подход позволяет успешно контролировать состояние различных территориально распределенных объектов. Тем не менее до настоящего времени остается открытым вопрос о выборе периодичности отправки собранных данных диспетчеру по указанному каналу связи. С одной стороны, необходимо стремиться к минимизации беспроводного трафика, с другой следует предусматривать своевременное получение информации об опасных тенденциях в изменении параметров ГС для предупреждения аварийных ситуаций. Данная статья анализирует эту проблему. Авторы предлагают производить корректировку первоначально установленного периода обновления информации о состоянии ГС, принимая во внимание результаты прогнозирования тенденций изменения контролируемых параметров на основе алгоритма Хольта.
