Abstract

In the Philippines, using renewable energy sources to generate electricity for the growing sectors of the country?s industry will alleviate the carbon emissions to the atmosphere. According to the Department of Energy, there will be a 40 megawatt increase in the exploration and utilization of renewable energy by the end of year 2017. As the government?s corporate vehicle in the promotion, development and implementation of renewable sources of energy in the country, Philippine National Oil Company Renewables Corporation (PNOC RC) collaborated with National Irrigation Administration (NIA) to harness hydropower from irrigation systems. The project for the connection of one (1) megawatt embedded hydropower generator to the 13.2kV distribution line of Nueva Ecija II Electric Cooperative Area 2 (NEECO II Area 2) is included in the collaborated projects of the two (2) companies. In compliance to the requirements set by the Energy Regulatory Commission (ERC), through the Philippine Distribution Code, PNOC RC conducted a distribution impact study. This field practice report provides an analysis on the distribution impact study conducted by PNOC RC for the connection of one (1) megawatt embedded hydropower generator to the NEECO II Area 2 distribution system. The input data for this study were gathered from the electric cooperative of the target area. ETAP 12.0 was used to evaluate the distribution system?s short circuit infeeds through short circuit analysis, power quality through power flow analysis, and the coordination of the protection system through coordination study. The field practice report assessed the condition of the distribution line before and after the connection of the new generating unit to the existing distribution line. And based on the results of the distribution impact study conducted by PNOC RC after the connection of the embedded generating unit to the 13.2kV distribution line of NEECO II Area 2, the proposed embedded generator?s short circuit contribution will be 0.13kA only. The connection of the proposed embedded generator will improve the steady-state voltage of the system from 5.92% to 0.21% during off-peak demand period and from 12.19% to 4.25% during peak demand period. The protective devices are sufficient to protect the system from maximum fault current that will occur in it but there is a need to enhance the compatibility of some protective devices.
