The purpose of work: designing a system of automated management of mine
electro supply which allows making regulation of operating modes of mine technological devices with the purpose of
electricity consumption decreasing by these devices during the periods of day with the greatest cost of the electric
power.
For achievement of an object in view it is necessary to solve a number
of problems:
- To develop means of the registration and the control of the electric power;
- To develop means for transferring information about conditions of technological devices of mine;
- To develop models of a power consumption of technological devices of mine.
Novelty of this development is in the fact that at occurrence of a situation
when at the given operating mode a current consumption exceeds the declared value, the developed system gives out
commands in system of automation of the set device on regulation of its operating mode, instead of on switching-off.
Now there are the following means of the control and management of
mine electro supply:
- the complex of telemechanical devices UTSh (УТШ) – is intended for the telesignalization of objects discrete
conditions, telemetering of current and integrated values of parameters, telecontrol of objects with discrete
conditions in systems of operatively-dispatching and automated management of collieries technological processes;
- device "Wind-1М" (Ветер-1М) – is intended on telemechanical management of local airing fans (LAF) and information
transmitting from gauges which characterize LAF conditions, air supply in to a working face, metane concentration over
established by safety norms;
- The complex of the management electro supply point equipment OPUE (ОПУЭ) – is intended on a dispatcher workplace
adjustment in automated control system of power supply;
- The equipment APV (АПВ) of repeated switching on – is intended on switching on of an element of electro supply
system which deenergizing has occurred as a result of emergency stop. Switching on is possible, if the reason of
deenergizing is eliminated;
- The equipment of reserve switching on AVR (АВР) – is provided in all cases when breaks electro supply causes losses
considerably exceeding costs of device AVR installation.
One of preliminary results of work is the mathematical model of process of
a current consumption stationary devices of mine named after M.I. Kalinin. By means of this model there have been
carried out researches which allow to optimize current consumption process.
As a result of modeling schedules of day consumption of active capacity have
been received (fig. 1), a day energy consumption (fig. 2), day expenses for the electric power (fig. 3).
Figure 1 – The schedule of daily consumption of active capacity
Figure 2 – The schedule of daily current consumption
Figure 3 – The schedule of daily expenses for the
electric power
In the further the improvement of the resulted model is planned. Thus, one
of master’s works problems – modeling of a power consumption of technological installations of mine can be solved.
Development of such model will allow to reveal the optimal, from the point of view of the electric power economy and
technological process, device’s operating modes and to use them as a basis for developed system.
Development of means of the account of the electric power and means of
information transfer about a conditions of technological devices of mine will allow constructing a system with use
of modern element base, that, in turn, will raise speed, accuracy and reliability of automation system.
