Abstract: 

IN ZABOL ONE OF THE SISTAN AND BALOCHESTAN PROVINCE CITY THE HEAVEY STORM CAUSE LOTS OF PROBLEM ON HV SUBSTATION DURING POWER DELIVERY. THE DUST DUE TO HEAVY WINDS IN THE AREA FORMS A LAYER ON ALL THE EQUIPMENTS AND IT WILL AFFECT THE MECHANICAL AND ELECTRICAL OPERATION OF THE APPARATUS. THE OPERATIONAL SIGNALS OF CONTROL EQUIPMENTS DUE TO THE DUST ON THEIR CONTACTS CAN NOT BE SEND OR RECEIVE. THIS WILL REDUCE THE RELIABILITY OF INTERLOCKING CONDITION, BYPASS THE PROTECTION SYSTEM BY USING C.B IN LOCAL POSITION SIGNAL AND RAISES THE TEMPERATURE OF APPARATUS WHICH WILL AFFECT THE STABILITY AND REDUCE THE RELIABILITY OF NETWORK. THE OPERATORS COMPLAIN ABOUT THIS EQUIPMENT HAS BEEN REACHED. DUE TO THESE PROBLEMS THE DUSTING OF SUBSTATION’S EQUIPMENT WILL BE LESS THAN ONE MOUNTH AND THE C.B OPERATION WILL BE AFFECTED AND IT MAY CAUSE SOME EVENTS FOR THE OPERATOR & EQUIPMENT IN SUBSTATION. AFTER INVESTIGATION REGARDING THIS TYPE OF SUBSTATION TO OVERCOME THE ABOVE PROBLEM SOME SUGESTION AND SUITABLE SOLUTION FROM MOST OF MANUFUCTURERS AND ELECTRIC INDUSTRY STANDARD HAS BEEN PURPOSED. IN THIS PAPER, SUBSTATION IN OPERATION HAS BEEN CONSIDERD AND SOLUTION IN TWO PARTS HAS BEEN SUGGESTED FOR THE PROVINCES WHICH WILL BE AFFECTED BY HEAVY WINDS. THE RELIABILITY OF NETWORK CAN BE INCREASED AND THE AFFECT OF HEAVY WINDS IN SUCH PROVINCES CAN BE REDUCED BY SUGGESTED METHODS.
