Determining Reliability Parameters for a Closed-Cycle Small Combined Heat and Power Plant

Abstract

The paper provides numerical values of the reliability parameters for independent power sources within the ambient temperature and output power range corresponding to the operation under the climatic conditions of Eastern Siberia and the Far East of the Russian Federation. We have determined the optimal values of the parameters necessary for the reliable operation of small CHP plants (combined heat and power plants) providing electricity for isolated facilities.

Numerical Analysis of Integral Characteristics for the Condenser Setups of Independent Power-Supply Sources with the Closed-Looped Thermodynamic Cycle

“…01080-p. 5 The system of nonstationary differential equations (1) - (7) with the corresponding initial (9) and boundary (9) -(16) conditions was solved by the finite difference method [10]. The difference analogs of differential equations were solved by the locally-one-dimensional method.…”

“…It leads to reducing the gas pipeline system safety in whole [5]. In particular, according to the data of enterprise operating the power-supply plants there are several causes of technical emergency: the loss of flame for a fuel burner (about 21 % from all quantity of breakdowns), the mechanical problem for a turbine (about 25 %) and the extremely high temperature in a condenser (about 20 %).…”

Operation reliability analysis of independent power plants of gas-transmission system distant production facilities

“…Nevertheless, often there are failures of this equipment which negatively affect functioning of the gas transmission system. Thus the analysis of statistical data showed [1] that one of basic reasons of violations of operation of a power source is appearance of extremely high value of temperature of working substance on an output from the condenser.
