• Calculation and the analysis of technical and economic indicators of separate units and power plant in general and also determination of standards for the approved models of calculation of nominal and normative indicators.
• Calculation of a specific consumption of conditional fuel on supply of electricity it is also warm and also determination of specific fuel consumption on power plant taking into account operational change of structure and the scheme of turning on of the equipment and calculation of own needs.
• Calculations and justification of the planned amounts of electricity production and a holiday of heat to external consumers and also costs for own and economic needs.
• Diagnostics of profitability of the boiler and turbine equipment and distribution of electric and heat loads between units taking into account differences in levels of thermal profitability.
• Operational accomplishment of calculations for optimization of the trade delivery schedule of the electric power and also calculations for forecasting and more detailed planning of generation and consumption of electrical energy and power for increase in cost efficiency of power plant in modern conditions of wholesale market of the electric power.

Characteristic and criteria of a system

For increase in profitability of functioning of an information system and ensuring its development when preserving invested funds, the software of MES-T2 2010 has the following characteristics and criteria:

• Modularity. Allows to reduce costs at change of functionality of a system due to variation of configurations of its separate elements.
• Openness. The requirement is aimed at a system possibility – to interact with other software according to certain standards.
• Scalability of software for a broad spectrum of system configurations from the isomorphic workstation to a corporate information system.
• Existence of an effective system of recovery of partial operability of a system in force majeur situations, etc.
• Choice of possible system provider. It is necessary to select such firm which will not disappear after a while. At the same time to hope for normal maintenance.
• Information search and convenience of work of users. Simplicity and convenience of work can sometimes be a decisive factor when choosing a system, especially if several almost similar software products are compared. Besides, this criterion indirectly testifies to qualification of developer company.
• The flexibility of a system is important criterion of its choice if the enterprise is not going to stand still i.e. if it is going to develop, improve the activity or just functions in the conditions of permanent change of external conditions.
• It makes sense to speak about ease of implementation if the enterprise is strictly limited in the deadlines and forces necessary for reduction of a system in operating condition.
• The replicability of a system (or, in other words, the number of its implementations) is a serious argument which helps to make the final decision when choosing the automation system.
• Domestic or foreign system. The following criteria are defining: functional completeness and "functional cost", i.e. shares of the systems capabilities used by the client for the money spent by him.
• System level. Functional completeness of proposed solution as it was already shown above, - one of the major criteria on the basis of which it is necessary to make selection. The choice of a system which has a limited set of opportunities will lead to what the enterprise will be forced to spend after a while perhaps, great efforts to the solution of the rest of problems.

InformSystem: Warning of emergency situations at power plants

The innovation MES System "MES-T2 2010" in addition to automation of calculations of TEI can easily implement all methods on warning of emergency situations at power plants since I in the past, working as 10 years at nuclear power stations, very densely dealt with this problem, especially, after the Chernobyl accident. But on nuclear power stations, without speaking about thermal, still there is no hint on automated systems of warning of emergency situations even.

The order of the Ministry of Energy of the Russian Federation of June 30, 2003 No. 265 approves the INSTRUCTION of software to WARNING AND ACCIDENT ELIMINATION ON THERMAL POWER STATIONS. The most characteristic emergency situations taking place on thermal power stations of all types and also an order of their warning and liquidation are given in this Instruction. Change No. 1 approved by Engineering Center UES Branch of JSC - ORGRES Company of 5/31/2004 is made to the text of the instruction.

However, in this instruction actually nothing is told about real warning of emergency situations. Especially about automation of this warning.

Nobody doubts that it is much simpler and much cheaper to prevent accident, than then to liquidate its. Why these questions a progressive tense and remain open? Any accident at power plant are huge losses for the generation companies.

And no regulation for 100% can save power plant from emergency. As a rule, accident always arises because of a human factor, especially at strong wear of the equipment since the operational personnel have no sufficient support on the automated diagnostic aids of this emergency situation.

When the emergency situation arises because of one factor, its operational personnel still somehow can prevent, being guided by regulations and experience. But when there is a chain of these factors, the person is powerless, to undertake something since he is elementary lost. And because of delay already nothing can be made. Also there is an explosion …

But the emergency situation arises not at once, and gradually. It as the snake who at first slowly and imperceptibly creeps and then snatches very quickly and fatally bites.

Here only after accident there is also a regret that there is no system on early detection of these accidents. So let's those consider possible and easily implementable options of warning of emergency situations.

Exists three real mutually supplemented approach: threshold, resource and logical. In this case we do not consider here protection which signal about already come emergency situation. The problem of warning of an emergency situation is in excluding operation of these abnormal protection since abnormal protection completely do not exclude emergence of large-scale accident. And operation of abnormal protection leads to unplanned stops that, naturally, is economically unprofitable.

And so, the threshold method which is on all nuclear power stations is the most elementary and actually the most inefficient. Threshold diagnostics provides signaling at an exit of analog signals for an upper setting, i.e. exceeding of pressure or temperature from face value.

The resource method provides dual control of degree of wear of the equipment and set of values of analog parameters on this equipment. Here the simple principle is used that the pipe has smaller wear, the it will sustain bigger value of pressure and temperature. Therefore at bigger wear of the specific equipment and a specific section of the pipe smaller extreme values of controlled parameters should them be ordered.

The logical method provides control of actions of operational personnel for management of power plant. Any implementation of the equipment, as well as its output from work, takes place strictly regulated stages of change of value of the corresponding discrete signals: included or disconnected. Therefore at change of value of the next switch statuses of adjacent switches and, if necessary, value of analog parameters are checked. If the logical condition is satisfied, then control is exercised, in an opposite case the report about incorrect actions with the correct hint is given.

Thus, the MES Production management system of power plant will ensure high-economic and trouble-free functioning of power plant that is especially important in modern market conditions.
