The power crisis management plan
Ministry of Energy (MOEN) has a policy to make country Energy security by provided adequate and reliability of energy. The Energy crisis management preparation plan is the one plan that initiated to support country energy security. MOEN assigned EPPO to develop the Implementation Plan for the energy crisis and exercise to face the crises that happen in the future. EPPO has appointed a working group to prepare a plan for the electricity crisis. This group is responsible to study and introduce guideline for the management of the electricity system when the country faced to the crisis of energy. This is included the power crisis that formation in according to the current electricity situation. The working group has compiled a definition of energy crisis; mobilize the information on energy crisis preparation from the past and the current action plan for the power crisis management. WG has develop scenario on energy situation, analyzed and defined energy crisis and proposed management guidelines under the crisis scenario as follows.
1. Refer to the information from the past, almost of the crisis occurred in the EGATT system. It can be classified into three main scenarios.
1.1 The emergency on power generation system, this consist of the trip in power plants and the crashed of fuel feeding system which affects to reduce the frequency of the power system, to dropped voltage in some areas, to step down the spinning reserve levels, to make some areas power blackout and also affect to rise cost of electricity by utilizing fuel oil and diesel fuel to replace natural gas volumes that are missing.
1.2 The emergency on transmission system, this consist the collapse of electrical transmission towers by theft and the grid trip in many circuits. It is affected to low down the frequency and the security of transmission system, caused the Partial Blackout in the northeast zone and power outages in some areas.
1.3 The emergency on power equipment such as explosion of devices in the UPS System of National Control Center (NCC), the explosion and fire at transformer substation, flash over on 3 phase breaker and blade which resulted in a lack of control or out of control of NCC and blackout at power station occure. For emergencies that occur with Metropolitan Electricity Authority (MEA) and the Provincial Electricity Authority (PEA) is caused by the inadequate of EGAT generation system, disaster, the riots, making the recovery of power system back to normal use more time.
2. Action Plan for the energy crisis of the 3 electricity authority of Thailand was formulated 3 sub-action plan, The action plan for organization risk management , The action plan for facing emergency or abnormal events and the action plan for organization communication in emergency event, which was aim to protect Transmission system Power Distribution System from damage when crisis occur and to continuously delivery electricity service to the consumers during the crisis event.
2.1 The organization risk management plan of the 3 Authorities are as follows;
EGAT | Plan for Organization Risk Management, the team of EGAT Deputy on the transmission System, in 2009, classifies risks into 6 areas: (1) the strategic and competition risk, (2) the financial risks (3) transmission system operations and the general operations risk (including information risk), (4) personnel risk (5) the communities and the environment risk, and (6) regulatory compliance risks. If any risks are linked and affect the operational or strategic issues of EGAT plans are set up to manage the risk in that area. |
MEA | Organization risk management plans to prevent damage that may occur in the distribution system of the MEA. This is classified the risk into 5 areas, (1) antenna feed line damage that may cause harm to life and property, (2) damage to the distribution system and service due to natural disasters and other threats, (3) the loss of life and property due to the electrical system and service delays, (4) violation of MEA property is an upward trend, and (5) electrical equipment that is defective causing power outages and have 6 risk management plan to support the operation. |
PEA | It has the monitoring system to support the business operations Management. The emergency events that affect/interrupt the business of PEA are as follow; (1) the 115 kV transmission line (2) power station (3) the 22-33 kV distribution system kV (4) the 400-230 V distribution system with a prioritization of action to recover and to assess the impact on business, The probability of irregular events occurring and It is defined programs / activities and responsible resource use in the operation. |
2.2 Action Plan for emergencies: the 3 authorities are formulated the action plan for emergency situations as follows.
EGAT |
It develop 3 action plan for facing emergency event as follow; 1. Manual for coordination of the electrical control system and Instructions electrical blackout 2. Blackout Restoration Plan 2010 3. The emergency plan for generation system or natural gas pipelines interruption 2010 4. Contingency plans in case the electric power computers control system disruptions 5. The national electric power system control center evacuation plan 6. Manual for emergency plan in case of high voltage transmission towers collapsed 7. Manual for emergency plan in case of flooding 8. Manual for emergency plan in case of the wreck 9. Manual for emergency plan in case of fire. |
MEA | Disaster Prevention and Mitigation Plan |
PEA | PEA Action Plan in case of unusual events. |
