В условиях нестабильного финансирования мероприятий по модернизации энергетического хозяйства в эксплуатации находится большое количество комплектных распределительных устройств (КРУ) предыдущих годов выпуска, в общем трудоспособных, но укомплектованных устаревшими коммутационными аппаратами, имеющими полностью исчерпанный ресурс или такой, что приближается к исчерпанию. Понятно, что продолжение эксплуатации таких КРУ – не прихоть беззаботной жизни, а жестокая необходимость, обусловленная нехваткой средств на приобретение современного оборудования.

Retrofit: economic solution of urgent problems

Under conditions of unstable funding of measures on modernization of energy facilities, large number of switchgear and control gear of previous years’ production, in general, able to work, but completed with outdated switching devices, having completely expired resource or one that is close to expiration are in operation.

Optimization of charge of generators of own power stations at jsc «MMK»

An article considers obtaining of the optimal value of electrical energy purchased by industrial enterprise with own sources of electrical energy and optimal values of generators’ power taking into account active power losses in network. Algorithm based on the method of dynamic programming and algorithm that takes into account losses, based on the method of coordinate-wise descent are described. Results of calculation for JSC «MMK» are presented.
